1. Yin, Wupeng. A Simplified Onsite Image-Registration Approach for Radiosurgery by Partial CT.

Degree: MS, Biomedical Engineering (Engineering), 2012, University of Miami

Stereotactic radiosurgery (SRS) is a kind of method of radiation therapy that uses three-dimensional computerized imaging to precisely guide a high-powered X-ray beam to deliver a concentrated dose of radiation to the abnormal area of the body. This therapy can efficiently and successfully treat many different types of tumors, either benign or malignant. Commonly used radiosurgery treatments are applied by CyberKnife or Gamma Knife through Stereotactic mechanism. Stereotactic radiosurgery can be assisted by two and three dimensional imaging during a course of radiation treatment. This is usually called Image-guided radiation therapy (IGRT), which utilizes the imaging coordinates to direct radiation beams to follow the actual radiation treatment plan. The image-guided system is the essential item to enable superior accuracies in the dose delivery by locating the patient’s instantaneous position during radiation treatments. In CyberKnife system current setup, two X-ray imaging sources and cameras are orthogonally mounted around the patient allowing instantaneous X-ray images to be obtained. This thesis presents a method that uses the technique of computed tomography, called partial CT, to guide the stereotactic surgery and significantly simplifies the image registration procedure by one set of X-ray sources and radiation detectors. The image processing for the partial CT is based on mutual information algorithm, a technically successful method, which ensures the accuracy of the image guidance system. All the experiments are demonstrated with respect to the CyberKnife system. Advisors/Committee Members: Weizhao Zhao, Xiaodong Wu, Jorge Bohorquez.

2. Li, Xiping. Web-based Medical Imaging Simulation System for Education and Research.

Degree: PhD, Biomedical Engineering (Engineering), 2011, University of Miami

In this work, a major effort has been made to establish an Internet accessible system for medical imaging simulation as a convenient service under the cloud computing environment. First, an Internet accessible, medical imaging education platform has been developed. It includes teaching and dynamic assessment tracking system for five commonly used imaging modalities. The system is integrated by the open source MySQL database software that manages updating materials and also tracks students’ learning engagements, which allow the reliability and appropriateness of the on-line teaching material and assessment methods to be optimized. The evaluation results have shown increased learning gains promisingly. Second, a prototype simulation service platform has been established. It is based on a job-oriented work flow to provide different kinds of service to users to perform medical imaging simulation. These simulations not only include the straightforward CT data reconstruction based on Radon transform, but also the sophisticated PET imaging simulation based on GATE as well. The QGATE’s client-server configuration can manage the GATE system to queue and monitor the submitted simulation scripts and return simulation results. The system is suitable for classroom training and easy to use for students or new users to the field of nuclear medicine imaging simulation. Finally, based on the developed simulation platform, a simulation study on PET imaging has been carried out. Event-based dynamic justification method has been tested based on the phantoms generated by NCAT associated with different breathing signals. The results show its potential capability of motion correction for PET data acquisition. Advisors/Committee Members: Weizhao Zhao, Jorge Bohorquez, Mike Georgiou, Fabrice Manns, Xiaodong Wu.

3. Lu, Li-Pin. Simulation Software and Hardwarefor Teaching Ultrasound.

Degree: MS, Biomedical Engineering (Engineering), 2008, University of Miami

Over the years, medical imaging modalities have evolved drastically. Accordingly, the need for conveying the basic imaging knowledge to future specialists and other trainees becomes even more crucial for devoted educators. Understanding the concepts behind each imaging modality requires a plethora of advanced physics, mathematics, mechanics and medical background. Absorbing all of this background information is a daunting task for any beginner. This thesis focuses on developing an ultrasound imaging education tutorial with the goal of easing the process of learning the principles of ultrasound. This tutorial will utilize three diverse approaches including software and hardware applications. By performing these methodologies from different perspectives, not only will the efficiency of the training be enhanced, but also the trainee?s understanding of crucial concepts will be reinforced through repetitive demonstration. The first goal of this thesis was developing an online medical imaging simulation system and deploying it on the website of the University of Miami. In order to construct an easy, understandable, and interactive environment without deteriorating the important aspects of the ultrasound principles, interactive flash animations (developed by Macromedia Director MX) were used to present concepts via graphic-oriented simulations. The second goal was developing a stand-alone MATLAB program, intended to manipulate the intensity of the pixels in the image in order to simulate how ultrasound images are derived. Additionally, a GUI (graphic user interface) was employed to maximize the accessibility of the program and provide easily adjustable parameters. The GUI window enables trainees to see the changes in outcomes by altering different parameters of the simulation. The third goal of this thesis was to incorporating an actual ultrasound demonstration into the tutorial. This was achieved by using a real ultrasound transducer with a pulse/receiver so that trainees could observe actual ultrasound phenomena, and view the results using an oscilloscope. By manually adjusting the panels on the pulse/ receiver console, basic A-mode ultrasound experiments can be performed with ease. By combining software and hardware simulations, the ultrasound education package presented in this thesis will help trainees more efficiently absorb the various concepts behind ultrasound.
