▼ Direct volume rendering (DVR) is a volume visualization technique that has been proved to be a very powerful tool in many scientific visualization domains. Diagnostic medical imaging is one such domain in which DVR provides new capabilities for the analysis of complex cases and improves the efficiency of image interpretation workflows. However, the full potential of DVR in the medical domain has not yet been realized. A major obstacle for a better integration of DVR in the medical domain is the time-consuming process to optimize the rendering parameters that are needed to generate diagnostically relevant visualizations in which the important features that are hidden in image volumes are clearly displayed, such as shape and spatial localization of tumors, its relationship with adjacent structures, and temporal changes in the tumors. In current workflows, clinicians must manually specify the transfer function (TF), view-point (camera), clipping planes, and other visual parameters. Another obstacle for the adoption of DVR to the medical domain is the ever increasing volume of imaging data. The advancement of imaging acquisition techniques has led to a rapid expansion in the size of the data, in the forms of higher resolutions, temporal imaging acquisition to track treatment responses over time, and an increase in the number of imaging modalities that are used for a single procedure. The manual specification of the rendering parameters under these circumstances is very challenging. This thesis proposes a set of innovative methods that visualize important features in multi-dimensional and multi-modality medical images by automatically or semi-automatically optimizing the rendering parameters. Our methods enable visualizations necessary for the diagnostic procedure in which 2D slice of interest (SOI) can be augmented with 3D anatomical contextual information to provide accurate spatial localization of 2D features in the SOI; the rendering parameters are automatically computed to guarantee the visibility of 3D features; and changes in 3D features can be tracked in temporal data under the constraint of consistent contextual information. We also present a method for the efficient computation of visibility histograms (VHs) using adaptive binning, which allows our optimal DVR to be automated and visualized in real-time. We evaluated our methods by producing visualizations for a variety of clinically relevant scenarios and imaging data sets. We also examined the computational performance of our methods for these scenarios.

▼ Volumetric medical imaging is an indispensable data in patient management by non-invasively visualising human organ system. A wide range of research has been conducted to provide effective visualisation of medical imaging volumes, by introducing conventional 2D image slice viewing and recent 3D volume rendering techniques. They have been demonstrated in different medical imaging modalities and diverse clinical applications. The recent advances in software platforms / display technologies have been explored for their potentials to bring new capabilities and features to volume visualisation. Web technologies enable ubiquitous computing for complex 3D rendering techniques through standard Web browsing software. Mixed reality (MR) head-mounted display (HMD) technology can deliver an immersive and natural way in which humans perceive and interact with the visualisation. This thesis hypothesises that utilisation of these two emerging technologies can bring new features to medical imaging visualisation. Two medical imaging visualisation systems are proposed. Firstly, a Web-based visualisation system is proposed to allow multi-disciplined clinicians to use personal devices for collaborative visualisation. We developed medical volume visualisation features, such as multi-modal visualisation and visualising personal data, and designed a visualisation sharing mechanism in a clinical context. Secondly, MR-HMD visualisation system is introduced with a new intuitive interaction mechanism where the users can employ a tangible planar object in their physical environment to navigate and interact with virtual 3D visualisation in the same physical coordinates. We developed an algorithm to track and locate the planar object without a marker by exploiting the depth camera in the Microsoft HoloLens. We evaluated two systems by demonstrating them in clinically relevant simulated scenarios with a variety of medical imaging datasets. We also examined their computational performances.

O projeto de funções de transferência é um interessante problema que recebe muita atenção da comunidade de visualização. Diversas pesquisas tem sido conduzidas para criar melhores ferramentas e técnicas que trabalham com dados volumétricos. Existem duas grandes classes de dados: volumes estruturados e volumes não-estruturados. A maioria dos trabalhos anteriores apenas se refere a dados estruturados. Este trabalho possui dois grupos de contribuições. O primeiro diz respeito ao problema clássico de especificação de funções de transferência. Primeiramente é desenvolvido o conceito de Ensembles, que são funções de transferência desenvolvidas a partir da combinação de funções anteriores e mais simples. Também é apresentada uma abordagem de key-framing para manipular dados que variam no tempo. O segundo grupo de contribuições é um estudo aprofundado sobre o comportamento de dados não-estruturados. Problemas críticos foram descobertos e tratados para permitir uma integração quase perfeita de ferramentas usadas para dados estruturados em dados não-estruturados. Os resultados mostram a melhoria de qualidade de histogramas, e também o sistema de desenvolvimento de funções de transferência. Trabalhos futuros são sugeridos para utilizar a versão melhorada do histograma de gradiente-magnitude, assim como a exploração de novos modelos de bordas.

Transfer function design is an important problem that receives much attention from the visualization community. Several researches have inspired the creation of better tools and techniques to deal with volumetric datasets. There are two major classes of datasets, namely structured and unstructured grids. Most of the previous work has only addressed structured data. This work presents two groups of contributions of different nature. The first contribution is related to the general problem of transfer function design. It introduces the concept of ensembles, which are complex transfer functions created from standard types. It also presents a key-frame based approach to handle time-varying sequences. The second group of contributions is related with a study on several characteristics of unstructured data. Problems have been discovered and addressed to allow a seamless integration of classical structured grids tools to unstructured data. This work includes results that show improvements on a statistical analysis of the data, as well as the developed transfer function design system. Further work is suggested to take advantage of the enhanced version of the gradient-magnitude histogram, and explore different boundary model.

▼ High-order finite element methods, using either the continuous or discontinuous Galerkin formulation, are becoming more popular in fields such as fluid mechanics,solid mechanics and computational electromagnetics. While the use of these methods is becoming increasingly common, there has not been a corresponding increase in the availability and use of visualization methods and software that are capable of displaying visualizations of these volumes both accurately and interactively. A fundamental problem with the majority of existing visualization techniques is that they do not understandnor respect the structure of a high-order field, leading to visualization error.Visualizations of high-order fields are generally created by first approximating the field with low-order primitives and then generating the visualization using traditionalmethods based on linear interpolation. The approximation step introduces error into the visualization pipeline, which requires the user to balance the competing goals of image quality, interactivity and resource consumption. In practice, visualizationsperformed this way are often either undersampled, leading to visualization error, or oversampled, leading to unnecessary computational effort and resource consumption.Without an understanding of the sources of error, the simulation scientist is unable to determine if artifacts in the image are due to visualization error, insufficient mesh resolution, or a failure in the underlying simulation. This uncertainty makes it difficultfor the scientists to make judgments based on the visualization, as judgments made on the assumption that artifacts are a result of visualization error when they are actually a more fundamental problem can lead to poor decision-making.This dissertation presents new visualization algorithms that use the high-order data in its native state, using the knowledge of the structure and mathematicalproperties of these fields to create accurate images interactively, while avoiding the error introduced by representing the fields with low-order approximations. First, a new algorithm for cut-surfaces is presented, specifically the accurate depiction of colormapsand contour lines on arbitrarily complex cut-surfaces. Second, a mathematical analysis of the evaluation of the volume rendering integral through a high-orderfield is presented, as well as an algorithm that uses this analysis to create accurate volume renderings. Finally, a new software system, the Element Visualizer (ElVis),is presented, which combines the ideas and algorithms created in this dissertation in a single software package that can be used by simulation scientists to create accurate visualizations. This system was developed and tested with the assistance of the ProjectX simulation team. The utility of our algorithms and visualization system are then demonstrated with examples from several high-order fluid flow simulations.

▼ In this dissertation, we advance the theory and practice of verifying visualization algorithms. We present techniques to assess visualization correctness through testing of important mathematical properties. Where applicable, these techniques allow us to distinguishwhether anomalies in visualization features can be attributed to the underlying physical process or to artifacts from the implementation under verification. Such scientific scrutiny is at the heart of verifiable visualization - subjecting visualization algorithms to the same verification process that is used in other components of the scientific pipeline. The contributionsof this dissertation are manifold. We derive the mathematical framework for the expected behavior of several visualization algorithms, and compare them to experimentally observed results in the selected codes. In the Computational Science & Engineering communityCS&E, this technique is know as the Method of Manufactured Solution (MMS). We applyMMS to the verification of geometrical and topological properties of isosurface extraction algorithms, and direct volume rendering. We derive the convergence of geometrical properties of isosurface extraction techniques, such as function value and normals. For theverification of topological properties, we use stratified Morse theory and digital topology to design algorithms that verify topological invariants. In the case of volume rendering algorithms, we provide the expected discretization errors for three different error sources.The results of applying the MMS is another important contribution of this dissertation. We report unexpected behavior for almost all implementations tested. In some cases, we were able to find and fix bugs that prevented the correctness of the visualization algorithm. Inparticular, we address an almost 2 0 -year-old bug with the core disambiguation procedure of Marching Cubes 33, one of the first algorithms intended to preserve the topology of the trilinear interpolant. Finally, an important by-product of this work is a range of responsespractitioners can expect to encounter with the visualization technique under verification.

▼ In the last 30 years, medical imaging has become one of the most used diagnostic tools in the medical profession. Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) technologies have become widely adopted because of their ability to capture the human body in a non-invasive manner. A volumetric dataset is a series of orthogonal 2D slices captured at a regular interval, typically along the axis of the body from the head to the feet. Volume rendering is a computer graphics technique that allows volumetric data to be visualized and manipulated as a single 3D object. Iso-surface rendering, image splatting, shear warp, texture slicing, and raycasting are volume rendering methods, each with associated advantages and disadvantages. Raycasting is widely regarded as the highest quality renderer of these methods. Originally, CT and MRI hardware was limited to providing a single 3D scan of the human body. The technology has improved to allow a set of scans capable of capturing anatomical movements like a beating heart. The capturing of anatomical data over time is referred to as functional imaging. Functional MRI (fMRI) is used to capture changes in the human body over time. While fMRI’s can be used to capture any anatomical data over time, one of the more common uses of fMRI is to capture brain activity. The fMRI scanning process is typically broken up into a time consuming high resolution anatomical scan and a series of quick low resolution scans capturing activity. The low resolution activity data is mapped onto the high resolution anatomical data to show changes over time. Academic research has advanced volume rendering and specifically fMRI volume rendering. Unfortunately, academic research is typically a one-off solution to a singular medical case or set of data, causing any advances to be problem specific as opposed to a general capability. Additionally, academic volume renderers are often designed to work on a specific device and operating system under controlled conditions. This prevents volume rendering from being used across the ever expanding number of different computing devices, such as desktops, laptops, immersive virtual reality systems, and mobile computers like phones or tablets. This research will investigate the feasibility of creating a generic software capability to perform real-time 4D volume rendering, via raycasting, on desktop, mobile, and immersive virtual reality platforms. Implementing a GPU-based 4D volume raycasting method for mobile devices will harness the power of the increasing number of mobile computational devices being used by medical professionals. Developing support for immersive virtual reality can enhance medical professionals’ interpretation of 3D physiology with the additional depth information provided by stereoscopic 3D. The results of this research will help expand the use of 4D volume rendering beyond the traditional desktop computer in the medical field. Developing the same 4D volume rendering capabilities across dissimilar platforms has many challenges. Each platform…

▼ To aid diagnosis, treatment planning, and patient education, clinicians require tools to analyse and explore the increasingly large three-dimensional (3-D) datasets generated by modern medical scanners. Direct volume rendering is one such tool finding favour with radiologists and surgeons for its photorealistic representation. More recently, volume illustration — or non-photorealistic rendering (NPR) — has begun to move beyond the mere depiction of data, borrowing concepts from illustrators to visually enhance desired information and suppress un- wanted clutter. Direct volume rendering generates images by accumulating pixel values along rays cast into a 3-D image. Transfer functions allow users to interactively assign material properties such as colour and opacity (a process known as classification). To achieve real-time framerates, the rendering must be accelerated using a technique such as 3-D texture mapping on commod- ity graphics processing units (GPUs). Unfortunately, current methods do not allow users to intuitively enhance regions of interest or suppress occluding structures. Furthermore, addi- tional scalar images describing clinically relevant measures have not been integrated into the direct rendering method. These tasks are essential for the effective exploration, analysis, and presentation of 3-D images. This body of work seeks to address the aforementioned limitations. First, to facilitate the research program, a flexible architecture for prototyping volume illustration methods is pro- posed. This program unifies a number of existing techniques into a single framework based on 3-D texture mapping, while also providing for the rapid experimentation of novel methods. Next, the prototyping environment is employed to improve an existing method—called tagged volume rendering — which restricts transfer functions to given spatial regions using a number of binary segmentations (tags). An efficient method for implementing binary tagged volume rendering is presented, along with various technical considerations for improving the classifi- cation. Finally, the concept of greyscale tags is proposed, leading to a number of novel volume visualisation techniques including position modulated classification and dynamic exploration. The novel methods proposed in this work are generic and can be employed to solve a wide range of problems. However, to demonstrate their usefulness, they are applied to a specific case study. Ischaemic heart disease, caused by narrowed coronary arteries, is a leading healthconcern in many countries including Australia. Computed tomography angiography (CTA) is an imaging modality which has the potential to allow clinicians to visualise diseased coronary arteries in their natural 3-D environment. To apply tagged volume rendering for this case study, an active contour method and minimal path extraction technique are proposed to segment the heart and arteries respectively. The resultant images provide new insight and possibilities for diagnosing and treating ischaemic heart disease.

Explorer et comprendre des données volumétriques ou surfaciques est un des nombreux enjeux du domaine de l'informatique graphique. L'apparence de telles données peut être modélisée et visualisée en utilisant la théorie du transport lumineux. Afin de rendre une telle visualisation compréhensible, le recours à des matériaux transparents est très répandu. Si des solutions existent pour simuler correctement la propagation de la lumière et ainsi afficher des objets semi-transparents, offrir une visualisation compréhensible reste un sujet de recherche ouvert. Le but de cette thèse est double. Tout d'abord, une analyse approfondie du modèle optique pour le transport de la lumière et ses implications sur la génération d'images par ordinateur doit être effectuée. Ensuite, cette connaissance pourra être utilisée pour proposer des solutions efficaces et fiables pour visualiser des milieux transparents et semi-transparents. Dans ce manuscrit, premièrement, nous présentons le modèle optique communément utilisé pour modéliser le transport de la lumière dans des milieux participatifs, sa simplification si l'on réduit la situation à des surfaces et la manière dont ces modèles sont utilisés en informatique graphique pour générer des images. Deuxièmement, nous présentons une solution pour améliorer la représentation des formes dans le cas particulier des surfaces. La technique proposée utilise le transport lumineux comme base pour modifier le processus d'éclairage et modifier l'apparence et l'opacité des matériaux. Troisièmement, nous nous concentrons sur la problématique de l’utilisation de données volumétriques au lieu du cas simplifié des surfaces. Dans ce cas, le fait de ne modifier que les propriétés du matériau a un impact limité. Nous étudions donc comment le transport lumineux peut être utilisé pour fournir des informations utiles à la compréhension de milieux participatifs. Enfin, nous présentons notre modèle de transport lumineux pour les milieux participatifs, qui vise à explorer une région d'intérêt d’un volume.

Exploring and understanding volumetric or surface data is one of the challenges of Computer Graphics. The appearance of these data can be modeled and visualized using light transport theory. For the sake of understanding such a data visualization, transparent materials are widely used. If solutions exist to correctly simulate the light propagation and display semi-transparent objects, offering a understandable visualization remains an open research topic. The goal of this thesis is twofold. First, an in-depth analysis of the optical model for light transport and its implication on computer generated images is performed. Second, this knowledge can be used to tackle the problematic of providing efficient and reliable solution to visualize transparent and semi-transparent media. In this manuscript, we first introduce the general optical model for light transport in participating media, its simplification to surfaces, and how it is used in computer graphics to generate images. Second, we present a solution to…

Algoritmos para rendering de superfícies são rápidos, mas não são compatíveis com situações em que é necessário investigar estruturas internas em volumes. Algoritmos de rendering volumétrico direto são adequados para a exploração de estruturas volumétricas, mas são lentos quando comparados a um rendering de superfícies. Várias soluções híbridas foram propostas na literatura, sendo que uma delas, conhecida como VoS (Volume on Surface), foi proposta recentemente com o objetivo de aumentar a capacidade de investigação do conteúdo de volumes por meio de superfícies. VoS é uma técnica híbrida que permite mapear o conteúdo de um volume em superfícies extraídas do mesmo. A técnica executa lançamento de raios para mapear as informações do volume na superfície, possibilitando a visualização das estruturas internas do volume utilizando rendering de superfícies convencional. No presente trabalho estudamos a técnica VoS e propomos diversas modificações com o intuito de generalizar a técnica e tratar algumas de suas limitações. As novas soluções apresentadas permitem a utilização da técnica com volumes de voxels regulares, e geram imagens de melhor qualidade. Assim como a VoS, as duas novas versões implementadas, VoSm e VoSm*, têm o objetivo de melhorar o poder de investigação do rendering de superfícies, permitindo a exploração do conteúdo de volumes. A técnica VoS e suas variações oferecem uma ferramenta alternativa para aplicações em que a utilização de superfícies é uma solução natural.

Surface rendering algorithms are fast, but are not suitable in situations where internal volume structures must be displayed for investigation. On the other hand, Direct Volume Rendering algorithms are effective to support exploration of internal volume structures, but software implementations are slow as compared to surface rendering solutions. Several hybrid solutions have been proposed in the literature. One of such hybrid solutions, named as VoS (Volume on Surface), has been recently introduced with the goal of using surfaces to enhance volume investigation capability. VoS is a hybrid technique that maps volume contents to surfaces extracted from this volume. The technique performs ray casting to map the volume information onto the surface, thus enabling the visualization of internal volume structures using standard surface rendering algorithms. In this work we study the VoS technique and propose several modifications in order to generalize the technique and treat some of its limitations. The new solutions presented here enable applying the technique to volumes described as a regular grid of voxels and produce images of superior quality as compared to the original. As with VoS, the two novel implementations, VoSm and VoSm*, have the goal of improving the investigative power of a surface rendering display, supporting exploration of volumetric contents. VoS and its variations are alternative tools for applications where surface rendering is a natural visualization solution.

▼ Volume rendering is a research area within scientific visualisation, where images are computed from volumetric data sets for visual exploration. Such data sets are typically generated by Computer aided Tomography, Magnetic Resonance Imaging, Positron Emission Tomography or gained from simulations. The data sets are usually interpreted using optical models that assign optical properties to the volume and define the illumination and shading behaviour. Volume rendering techniques may be divided into three classes: object-order, image-order or hybrid methods. Image-order or ray casting methods shoot rays from the view plane into the volume and simulate the variation of light intensities along those rays. Object-order techniques traverse the volume data set and project each volume element onto the view plane. Hybrid volume rendering techniques combine these two approaches. A very popular object-order rendering method is called splatting. This technique traverses the volume data set and projects the optical properties of each volume element onto the view plane. This thesis consists of two parts. The first part introduces two new splatting methods, collectively called high-resolution splatting, which are based on standard splatting. Both high-resolution splatting methods correct errors of splatting by applying major modifications. We propose the first method, called fast high-resolution splatting, as an alternative to standard splatting. It may be used for quick previewing, since it is faster than standard splatting and the resulting images are significantly sharper. Our second method, called complete high-resolution splatting, improves the volume reconstruction, which results in images that are very close to those produced by ray casting methods. The second part of the thesis incorporates wavelet analysis into high-resolution splatting. Wavelet analysis is a mathematical theory that decomposes volumes into multi-resolution hierarchies, which may be used to find coherence within volumes. The combination of wavelets with the high-resolution splatting method has the two advantages. Firstly the extended splatting method, called high-resolution wavelet splatting, can be directly applied to wavelet transformed volume data sets without performing an inverse transform. Secondly when visualising wavelet compressed volumes, only a small fraction of the wavelet coefficients need to be projected. For all three versions of the new high-resolution splatting method, complexity analyses, comprehensive error and performance analyses as well as implementation details are discussed.
