▼ While various online multi-target tracking methods have been proposed recently, most of their runtime speed struggle at 1-10 frames per second for moderate crowded scenes. In this thesis, we present a novel real-time multi-target tracking system based on the tracking-by-detection framework. Our system is designed for tracking a variable number of interacting targets from a single, static, above shoulder camera, which is a general setting for video surveillance. One challenge in our approach is that when background subtraction is used for detecting moving targets, merged measurements occur frequently because of target interactions. To cope with the problem, we propose to use correlation filter based object detector to robustly separate the targets in merged measurements. Then, online object tracking assisted data association is used to solve the track-measurement assignment. To reduce computation load, our object tracking algorithm is assisted by correlations filter based trackers which share the same features used by our object detector. In addition, to recover partially occluded targets, we allow unconfident detections to be assigned to tracks whilst care is taken to avoid introducing additional false positives. We also analyze the online approximation to multi-channel correlation filters. Our experiments show that exact solution is more resistant to noisy channels than approximate solution. Evaluation on generally accepted datasets reveals that the proposed system is comparable to state-of-the-art methods in terms of performance while running several magnitudes faster. Additionally, we show that the proposed system can be readily implemented on the Texas Instruments TMS320C6678 DSP (C6678) without significant degradation in speed or performance. Details on efficient implementation of the system is also discussed. Especially, for computing Histogram of Oriented Gradients (HOG) feature, our optimized implementation runs at 60fps on VGA images on a single core of C6678, which is 10 times faster than a directly ported implementation.

▼ High-speed precision tracking is needed in a wide variety of motion control applications ranging from high-speed AFM(Atomic Force Microscope) operation, high-throughput manufacturing, to robotic operations. Challenges still exist in high-speed precision control of systems such as smart actuators with coupled hysteresis and dynamics. Although output tracking has been well-studied for linear systems, tracking with non-periodic tracking-transition switching for non-minimum phase linear systems still remains challenging, especially when multiple control objectives need to be achieved, including smooth transition from one output tracking session to the next one without inducing post-transition oscillations, input energy minimization without saturation under input amplitude constraint, and furthermore, minimization of the overall transition time. Moreover, further difficulties also arise in exploring the advantages of iterative learning control (ILC) in achieving precision but robust output tracking at high-speed to non-repetitive applications with online-generated desired trajectory, particularly for systems with complicated input-output behavior such as Hammerstein systems. The ILC framework can be extended, although for linear systems, to non-periodic output tracking via the superposition principle (SP), where the system response (output) to a linear combination of inputs equals to the same linear combination of the outputs to each individual inputs. Exploring the notion of the SP beyond linear systems is largely limited, as the nonlinearities are difficult to be modeled effectively and accurately. Therefore, challenges still exist in high-speed precision output tracking in emerging applications. In this dissertation, a multi-objective optimal tracking/transition under input constraints for non-periodic tracking/transition switching problem, and a learning-based approach for tracking control of Hammerstein systems are proposed. An approach to extend the previous work on smooth output transition and smooth tracking/transition switching to further achieve minimization of both input-energy and transition time under input amplitude constraints is proposed. The constrained input optimization problem is converted to an unconstrained input minimization problem, and then solved by utilizing an improved conjugate gradient method. The total transition time is further minimized via one dimensional search. The almost superposition of Hammerstein systems (ASHS) is developed, and then exploited for precision control of hysteresis-Hammerstein systems. We showed that for Hammerstein operator satisfying a Lipschitz condition, a weak form of the ASHS – the linear combination of outputs approaches to the response to the linear combination of the corresponding inputs with a different set of combination coefficients – exists when there are enough output elements. The strict form of the ASHS – the coefficients of the output and the input combination match to each other exactly – holds for a certain choice of the inputs.

ENGLISH ABSTRACT: Object detection and tracking are important components of many computer vision applications including automated surveillance. Automated surveillance attempts to solve the challenges associated with closed-circuit camera systems. These include monitoring large numbers of cameras and the associated labour costs, and issues related to targeted surveillance. Object detection is an important step of a surveillance system and must overcome challenges such as changes in object appearance and illumination, dynamic background objects like ickering screens, and shadows. Our system uses Gaussian mixture models, which is a background subtraction method, to detect moving objects. Tracking is challenging because measurements from the object detection stage are not labelled and could be from false targets. We use multiple hypothesis tracking to solve this measurement origin problem. Practical long-term tracking of objects should have re-identi cation capabilities to deal with challenges arising from tracking failure and occlusions. In our system each tracked object is assigned a one-class support vector machine (OCSVM) which learns the appearance of that object. The OCSVM is trained online using HSV colour features. Therefore, objects that were occluded or left the scene can be reidenti ed and their tracks extended. Standard, publicly available data sets are used for testing. The performance of the system is measured against ground truth using the Jaccard similarity index, the track length and the normalized mean square error. We nd that the system performs well.

Outomatiese bewaking poog om die uitdagings wat verband hou met geslote kring kamera stelsels op te los. Dit sluit in die monitering van groot hoeveelhede kameras en die gepaardgaande arbeidskoste, en kwessies wat verband hou met toegespitse bewaking. Die opsporing van voorwerpe is 'n belangrike stap in 'n bewakingstelsel en moet uitdagings soos veranderinge in die voorwerp se voorkoms en beligting, dinamiese agtergrondvoorwerpe soos ikkerende skerms, en skaduwees oorkom. Ons stelsel maak gebruik van Gaussiese mengselmodelle, wat 'n agtergrond-aftrek metode is, om bewegende voorwerpe op te spoor. Volging is 'n uitdaging, want afmetings van die voorwerp-opsporing stadium is nie gemerk nie en kan afkomstig wees van valse teikens. Ons gebruik verskeie hipotese volging (multiple hypothesis tracking ) om hierdie meting-oorsprong probleem op te los. Praktiese langtermynvolging van voorwerpe moet heridenti seringsvermoëns besit, om die uitdagings wat voortspruit uit mislukte volging en okklusies te kan hanteer.

▼ Achieving efficient and effective tracking remains a challenging task resorting from factors such as partial occlusion, background clutter, pose or illumination changes. Even though a tracker could follow basic procedures of tracking-by-detection to implement general object tracking, most state-of-the-art algorithms incorporate additional or sophisticated processing such as using auxiliary models so as to solve the challenges. This thesis presents novel methods on real-time general object tracking with auxiliary models. We study the feature selection along with the appearance model and motion model in video tracking algorithms. The categorization is yielded based on real applications utilizing features and models. In visual tracking, we propose two auxiliary models. One method utilizes generalized part-based appearance model and structure-constrained motion model as auxiliary. The appearance of the target object is modeled by the proposed generalized part-based appearance model, adaptively updated by an efficient structure learning scheme. In addition, we enhance the performance of our tracker by using a motion model, which employs a structure-constrained rule, that is, the change on the structure of the target object between consecutive frames is small. Another tracking method leverages layered detection that combines detection on two independent layers in a unified tracking-by-detection framework, one layer on the global level and the other on patch. According to the representation of the user-specified object of interest, the global level could distinguish the object against the background effectively, whereas the patch level is able to sample the patches of interest in the bounding box representation. Besides describing our own tracking methods, we compare diverse tracking algorithms in the literature using a public benchmark. During visual tracking, feature selection plays an important role. SIFT, SURF, HOG are commonly used. In this thesis, we study the problem of tracking man-made objects along the video sequence, and present a novel affine-invariant feature, Low-rank SIFT, which exploits the regular appearance property in man-made objects and achieves full affine invariance without needing to simulate over the affine parameter space. Our method seeks to leverage the low-rank prior to estimate the affine parameters for local patches directly and we propose a fast algorithm to compute parameters by introducing the Low-rank Integral Map. By automatically rectify the local patches to the low-rank forms, and perform conventional SIFT to solve rotation, translation and scaling ambiguity, our approach is able to perform feature selection in tracking with higher accuracy. With promising experimental results and observable qualitative improvement, the ideas of auxiliary models and affine-invariant features are blossoming. Further exploration on tracking will be conducted with more sophisticated models and more efficient calculating algorithms.

▼ As significant advances have been made in the computation devices, the mechanical technologies and the autonomy science, the public has recently found that having unmanned aerial vehicles(UAVs) involved in our work and daily lives is within the near future. However, despite the maturity of estimation, control and structure techniques, such applications require efficient planning of trajectories for UAVs to safely operate in cluttered environments, which remains a challenging problem and thus is worth our efforts. In this thesis, we present an online method for generating collision-free trajectories for autonomous quadrotor flight through cluttered environments. We consider the real-world scenario that the quadrotor aerial robot is equipped with limited sensing and operates in an initially unknown environment. During flight, an octree-based environment representation is incrementally built using onboard sensors. Utilizing efficient operations in the octree data structure, we are able to generate free-space flight corridors consisting of large overlapping 3-D grids in an online fashion. A novel optimization-based method then generates smooth trajectories that are both bounded entirely within the safe flight corridor and satisfy higher-order dynamical constraints. Our method computes valid trajectories within fractions of a second on a moderately fast computer, thus permitting online re-generation of trajectories for reaction to new obstacles. This method is also extended to address the challenging problem of tracking a moving target in cluttered environments using a quadrotor. Our online trajectory planning method generates smooth, dynamically feasible, and collision-free polynomial trajectories that follow a visually tracked moving target. As visual observations of the target are obtained, the target trajectory can be estimated and used to predict the target motion for a short time horizon. We propose a formulation to embed both the limited horizon tracking error and quadrotor control costs in the cost function for a quadratic programming (QP), while encoding both collision avoidance and dynamical feasibility as linear inequality constraints for the QP. Our method generates tracking trajectories in the order of milliseconds and is therefore suitable for online target tracking with a limited sensing range. We build a complete quadrotor testbed with onboard sensing, state estimation, mapping, and control, and integrate the proposed method to demonstrate the effectiveness of our approach.

▼ Product designers address the costs of assembly during the design process. Design process can be more efficient if assembly issues could be addressed early in its design process. Doing this requires the ability to assess assemblability among others. Assemblability refers to the ease of assembling the final product from its parts. Assemblability evaluation is applied by product designers for quantitatively estimating the degree of difficulty of the assembly. This helps in identifying areas of improvement, so as to reduce process time and production costs. This work focuses on assessing assemblability in a manual assembly and its importance in the earlier phases of design. Literature contains various methods for assessing assemblability (e.g. Boothroyd-Dewhurst method, the DFA house, Sturges DFA calculator and Sony DFA method). These methods are typically rule-based and their use requires insight and knowledge on the part of the designer. Further, the designer has to interpret and apply them differently in each specific and unique case. Literature also contains methods for ergonomic assessment of manual work and its link with assemblability. Both observation based ergonomic assessment such as RULA, REBA, VIDAR, LUBA and OWAS and instrumentation based ergonomic assessment using electro-goniometer and accelerometer are the techniques reviewed in this thesis for their suitability in assembly assessment. The most recent trend in the area is automation of the evaluation process. This thesis proposes an approach to automated assessment of assemblability using electromagnetic trackers. In spite of advances in industrial automation, manual assembly tasks continue to be an important feature of many industrial operations. The method proposed in the thesis is for the assessment of assemblability of manual assembly that combines both time and postural analysis. The tool used for the static analysis is called Rapid Upper Limb Assessment (RULA); for dynamic analysis a new method of time analysis is proposed that is based on the ratio of time spent in fine and gross motions carried out in an assembly process. The difficulty of assembly of a series of manual assembly tasks are carried out in a laboratory setting. Then by correlating this assessment with the feedback on the difficulty of these assembly task obtained from the subjects who carried out these tasks. The remaining work carried out as a part of this thesis is focussed on automating the process of carrying out the above assessment in an automated manner. Suitability of electromagnetic trackers as a means for automated capture of data necessary for executing the proposed assessment method is studied. Electromagnetic trackers have been used to capture postural data for various limbs of the assembly operators. Data from the limbs are then analysed to identify, to which limb movement signifies which sources of difficulty (i.e. reach, visibility, etc.) in assembly; for example reach difficulty is indicated by torso movement. Finally, the thesis proposes as a part of the future… Advisors/Committee Members: Chakrabarti, Amaresh (advisor), Gurumoorthy, B (advisor).

▼ ENGLISH ABSTRACT: Detection and tracking of moving objects (DATMO) is one of the core components necessary for autonomous navigation of a robot. The robot requires measurements of its environment, and uses these measurements to construct a representation of the dynamic objects in its environment. Once dynamic objects have been detected, the robot can use their locations and movement for autonomous functionality such as navigation, or collision prediction and avoidance. Of particular interest are vision-based sensors such as cameras, due to the amount of information they give about the environment. However, the amount of information causes difficulty regarding the interpretation and workable utilisation of the information. This thesis outlines a systematic approach for robust estimation of states for DATMO using stereo vision cameras. The mathematical basis of the camera geometry is derived. These include the camera projection transform, camera parameters, and epipolar geometry. Imagefeatures are obtained from both the left and right cameras and are matched. These matched image-feature pairs are triangulated to form 3D measurements of the moving objects in the robot’s environment. These 3D measurements are then used to filter the state estimates of the moving objects. Popular feature detection algorithms are expounded and investigated. ORB, KAZE, and A-KAZE are chosen for implementation and comparison. Factors pertaining to feature detection and matching, such as subpixel accuracy and matching strength, are weighed in light of a desired robust implementation. The data association problem, that is which objects in the environment caused which measurements, is addressed. Methods used to address the problem, such as global nearest neighbour, probabilistic data association, and multiple hypothesis tracking (MHT), are examined. A multiple hypothesis tracking solution that uses Bayesian statistics is used in order to reliably associate measurements to objects in the robot’s environment. Necessary approximations to the MHT approach are made and justified. The approximations result in a first-order approximation and a Gaussian mixture density description. The issue of unbounded associations is addressed and managed with techniques that remove, approximate, or prevent unnecessary state estimates. Algorithms are tested using the KITTI dataset in Python. LiDAR is used to evaluate the results of the algorithm. The computational cost of the algorithm is the biggest issue highlighted by the results. This is due to the complexity of the multiple hypothesis tracking solution and the large number of image-features used to ensure robust and reliable functionality. The results of the thesis demonstrate that there is philosophical conflict between the requirement of robust estimation on the filtering side, and the large number of measurements required from camera images. The complexity increases with the number of measurements, but many measurements are needed in order to provide a reliable representation… Advisors/Committee Members: Van Daalen, Corne E., Stellenbosch University.

▼ Repetitive Control (RC) seeks to converge to zero tracking error of a feedback control system performing periodic command as time progresses, or to cancel the influence of a periodic disturbance as time progresses, by observing the error in the previous period. Iterative Learning Control (ILC) is similar, it aims to converge to zero tracking error of system repeatedly performing the same task, and also adjusting the command to the feedback controller each repetition based on the error in the previous repetition. Compared to the conventional feedback control design methods, RC and ILC improve the performance over repetitions, and both aiming at zero tracking error in the real world instead of in a mathematical model. Linear Model Predictive Control (LMPC) normally does not aim for zero tracking error following a desired trajectory, but aims to minimize a quadratic cost function to the prediction horizon, and then apply the first control action. Then repeat the process each time step. The usual quadratic cost is a trade-off function between tracking accuracy and control effort and hence is not asking for zero error. It is also not specialized to periodic command or periodic disturbance as RC is, but does require that one knows the future desired command up to the prediction horizon. The objective of this dissertation is to present various design schemes of improving the tracking performance in a control system based on ILC, RC and LMPC. The dissertation contains four major chapters. The first chapter studies the optimization of the design parameters, in particular as related to measurement noise, and the need of a cutoff filter when dealing with actuator limitations, robustness to model error. The results aim to guide the user in tuning the design parameters available when creating a repetitive control system. In the second chapter, we investigate how ILC laws can be converted for use in RC to improve performance. And robustification by adding control penalty in cost function is compared to use a frequency cutoff filter. The third chapter develops a method to create desired trajectories with a zero tracking interval without involving an unstable inverse solution. An easily implementable feedback version is created to optimize the same cost every time step from the current measured position. An ILC algorithm is also created to iteratively learn to give local zero error in the real world while using an imperfect model. This approach also gives a method to apply ILC to endpoint problem without specifying an arbitrary trajectory to follow to reach the endpoint. This creates a method for ILC to apply to such problems without asking for accurate tracking of a somewhat arbitrary trajectory to accomplish learning to reach the desired endpoint. The last chapter outlines a set of uses for a stable inverse in control applications, including Linear Model Predictive Control (LMPC), and LMPC applied to Repetitive Control (RC-LMPC), and a generalized form of a one-step ahead control. An important characteristic is that this…

▼ Visual tracking is a fundamental task in computer vision. Numerous subsequent applications such as video semantic analysis call for reliable tracking results. In this thesis, we first delve into a tracker to analyze the most influential components for good performance. In particular, we propose a novel framework for tracker evaluation which decomposes a tracker into five parts: motion model, feature extractor, observation model, model updater, and ensemble post-processor. We find that the feature extractor plays the most important role in a tracker. Although the observation model is the focus of many studies, it often brings no significant improvement. Moreover, the motion model and model updater contain many details that could affect the result. The ensemble post-processor can also improve the result substantially when the constituent trackers have high diversity. Though we cannot cast all the existing trackers into the evaluation framework, we cover most of the popular ones. We believe the analyses are universal enough to enlighten some future research directions. Based on these analyses, we decide to apply advanced machine learning techniques for visual tracking. Particularly, we focus on the feature learning and ensemble post-processing parts. In feature learning, we try three different approaches which are based on online non-negative robust dictionary learning, stacked denoising autoencoder (SDAE) and convolutional neural network (CNN). In the first method, we present an online robust non-negative dictionary learning algorithm for updating the object templates, and devise a novel online projected gradient descent method to solve the dictionary learning problem. Our algorithm blends the past information and the current tracking result in a principled way. It can automatically detect and reject the occlusion and cluttered background, yielding robust object templates. For the next two methods, we build our methods on the idea of transfer learning. We propose to transfer generic image and object features which are learned offline to online tracking. Our first attempt is to train an SDAE using one million auxiliary natural images, and then transfer the encoder part of the SDAE as a feature extractor to online tracking. An additional classifier layer is appended to the top of the encoder in online tracking, then both the feature extractor and the classifier can be fine-tuned to adapt to appearance changes of the moving object. Our second approach is based on CNN. To tackle the disadvantages of the previous approach, we utilize CNN which is a more powerful deep learning model as demonstrated by many researchers in recent years. We further improve the vanilla CNN with objectness pretraining and structured output. Experiments on a recent benchmark [81] show the superiority of the proposed methods. For the ensemble post-processor, inspired by some recent studies on crowdsourcing, we propose a novel factorial hidden Markov model (FHMM) for aggregating structured output time series data. For efficient online inference of…

▼ Driven by the increasing demand for mobility and automation in both research and application domains, mobile robots have started to draw wide attention from researchers in academia as well as industry. Among the innumerable research topics in robotics, two fundamental issues lie in the technologies of location sensing and path planning. This thesis studies the two issues in real world environments which are inherently uncertain and dynamic. We address the location sensing issue with an active Radio Frequency Identification (RFID) based indoor location sensing technology. The technique uses adaptive temporal radio maps and reference points to enhance computation efficiency and offset environmental variations. In particular, we investigate the RFID tag signal characteristics in an indoor environment and analyze the feasibility of utilizing active RFID for location estimation. Then, we propose a data mining technique using deterministic methodology to achieve higher estimation accuracy and improved systematic properties including maintainability, scalability and cost. To address the issue of planning with imperfect information in dynamic environments, we propose a heuristic-based, anytime planning and replanning algorithm. Our research attempt is to combine the benefits of anytime and incremental planning to provide efficient solutions to complex, dynamic search problems. Besides, obstruction avoidance is taken care of by the anytime replanning within the available deliberation time. A case study of the research results is conducted with a prototype system. The system is built utilizing composition methodology. The location sensing and path planning subsystems are implemented as components such that they can operate and interoperate with the component-oriented software infrastructure through plug-and-play integration. The case study aims to provide qualitative analysis of the scientific methodologies and real world values behind the prototype as well as demonstrating its functionality and applicability in learning activities.

▼ Object tracking is important in various applications such as video surveillance systems, video annotation systems, and human interaction classification systems. Occlusion and noise are the most significant problems in object tracking. In order to overcome these problems, I introduce the temporal spatio-velocity (TSV) transform, which extracts pixel velocities from image sequences. The TSV transform appends the velocity axes to the image sequences and separates occluding objects based on their velocities. The TSV transform is derived from the Hough transform over windowed spatio-temporal images. I present the methodology of the transform and its implementation in an iterative computational form. The intensity at each pixel in the TSV image represents a measure of the likelihood of occurrence of a pixel with instantaneous velocity in the current position. Binarization of the TSV image extracts blobs based on the similarity of velocity and position. The TSV transform provides an efficient way to remove noise by focusing on stable velocities, and constructs noise-free blobs. In this dissertation, I introduce three applications using the TSV transform. The applications are (i) human interaction recognition system, (ii) object tracking system in occluding environments, and (iii) soccer player tracking system. The human interaction recognition system uses side-view image sequences and tracks persons walking on sidewalks. Then it recognizes the interactions between two persons such as “two persons meet from different directions” and “one person follows another person”. The system correctly tracks persons and recognizes the interactions between them. The object tracking system in occluding environments tracks moving objects behind static obstacles, such as trees and fences. Although the static obstacles divide moving objects into several pieces both temporally and spatially, the system correctly tracks the objects. The soccer player tracking system tracks soccer players and referees using the ordinary TV broadcasting images. Although the soccer players make complex movements and the camera moves frequently, the system correctly tracks the players and referees. Advisors/Committee Members: Aggarwal, J. K.

▼ Research in target pursuit using Unmanned Aerial Vehicle (UAV) has gained attention in recent years, this is primarily due to decrease in cost and increase in demand of small UAVs in many sectors. In computer vision, target pursuit is a complex problem as it involves the solving of many sub-problems which are typically concerned with the detection, tracking and following of the object of interest. At present, the majority of related existing methods are developed using computer simulation with the assumption of ideal environmental factors, while the remaining few practical methods are mainly developed to track and follow simple objects that contain monochromatic colours with very little texture variances. Current research in this topic is lacking of practical vision based approaches. Thus the aim of this research is to fill the gap by developing a real-time algorithm capable of following a person continuously given only a photo input. As this research considers the whole procedure as an autonomous system, therefore the drone is activated automatically upon receiving a photo of a person through Wi-Fi. This means that the whole system can be triggered by simply emailing a single photo from any device anywhere. This is done by first implementing image fetching to automatically connect to WIFI, download the image and decode it. Then, human detection is performed to extract the template from the upper body of the person, the intended target is acquired using both human detection and template matching. Finally, target pursuit is achieved by tracking the template continuously while sending the motion commands to the drone. In the target pursuit system, the detection is mainly accomplished using a proposed human detection method that is capable of detecting, extracting and segmenting the human body figure robustly from the background without prior training. This involves detecting face, head and shoulder separately, mainly using gradient maps. While the tracking is mainly accomplished using a proposed generic and non-learning template matching method, this involves combining intensity template matching with colour histogram model and employing a three-tier system for template management. A flight controller is also developed, it supports three types of controls: keyboard, mouse and text messages. Furthermore, the drone is programmed with three different modes: standby, sentry and search. To improve the detection and tracking of colour objects, this research has also proposed several colour related methods. One of them is a colour model for colour detection which consists of three colour components: hue, purity and brightness. Hue represents the colour angle, purity represents the colourfulness and brightness represents intensity. It can be represented in three different geometric shapes: sphere, hemisphere and cylinder, each of these shapes also contains two variations. Experimental results have shown that the target pursuit algorithm is capable of identifying and following the target person robustly given only a photo… Advisors/Committee Members: Western Sydney University.

Introduktion: Vid ekokardiografi används ultraljudsvågor med frekvens över 20 000Hz. Ultraljudssändare med piezoelektriska kristaller används för att generera ljudvågor som skickas ut i kroppen, reflekteras och sedan återvänder till kristallerna för att skapa en ultraljudsbild. Ejektionsfraktionen uttrycker hur stor del av den diastoliska volymen som pumpas ut i kroppen under systole och är en viktig parameter vid bedömning av den globala systoliska funktionen. Den rekommenderade metoden Simpsons biplan jämförs med Philips automatiska funktion a2Dq, som utgår ifrån speckle tracking principen, för bedömning av ejektionsfraktionen. Material och metod: 32 hjärtfriska testpersoner mellan 20–43 år inkluderades i tvärsnittsstudien. Apikala 4- och 2-kammarbilder insamlades ifrån testpersonerna och användes för beräkning av ejektionsfraktionen. Den manuella metoden Simpsons biplan grundas på operatörens utlinjering av endokardiet. Den automatiska funktionen a2Dq utgår ifrån 53 hjärtmodeller och placerar en region of interest automatiskt. Den semiautomatiska funktionen används genom att operatören modifierar region of interest men inte längden av vänsterkammaren. Resultat: Resultatet visade att det inte förelåg någon signifikant skillnad i mätvärdena av ejektionsfraktionen mellan de tre mätprinciperna. Den semiautomatiska och manuella metoden som är operatörsberoende hade likvärdiga mätresultat. Den automatiska funktionen erhöll totalt 6 mätvärden som hamnade utanför normalgränserna. Diskussion: Automatiska funktioner för bedömning av ejektionsfraktionen utvecklas snabbt och kräver utvärderingar. Automatiska mätningar har påvisats vara fördelaktiga då de inte är så tidskrävande som den manuella Simsons biplanmetoden. Tidsaspekten framhävs i de flesta studier dock på bekostnad av säkra mätresultat. Observationerna i denna studie påvisar att den automatiska funktionen inte är säker nog för användning. Konklusion: Enligt observationer ifrån denna studien rekommenderas att den automatiska funktionen ifrån Philips inte används.

Introduction: Ultrasound are soundwaves with frequencies above 20 000Hz. Piezoelectric crystals are used to generate sound waves that can be transmitted into the tissue and reflected back to the crystals to obtain an ultrasound image. The ejection fraction expresses how much blood the left ventricle pumps out with each contraction and is an important parameter for assessment of the hearts global systolic function. The recommended method Simpson´s biplane to assess ejection fraction is compared with Philips automatic function a2Dq, which is based on the principle of speckle tracking. Material and method: The study population included 32 tests subjects with age between 20-43 years old. The test subjects had no records of earlier heart pathologies. Apical 4- and 2-chamber images were collected for the purpose to measure the ejection fraction.…
