Biochemical Imaging of Gliomas Using MR Spectroscopic Imaging for Radiotherapy Treatment Planning
DownloadSpring 2014
This thesis discusses the main obstacles facing wide clinical implementation of magnetic resonance spectroscopic imaging (MRSI) as a tumor delineation tool for radiotherapy treatment planning, particularly for gliomas. These main obstacles are identified as 1. observer bias and poor...

Real-time MR imaging of the cancer patients undergoing external beam radiation treatment represents the next generation in image guided radiotherapy. However, the radio frequency (RF) coil of the MRI is exposed to the pulsed radiation of the linear accelerator in the systems where a medical...

Efficient data acquisition, transmission and post-processing for quality spiral Magnetic Resonance Imaging
DownloadFall 2011
Spiral Magnetic Resonance Imaging (MRI) has traditionally presented more technical and computational challenges compared to its traditional Cartesian counterpart, notably a susceptibility to blurring artifacts, especially when scan parameters are non-optimal, and a heavier computational load both...

Hybrid magnetic resonance imaging (MRI) and radiation therapy devices are capable of imaging in real-time to track intrafractional lung tumour motion during radiotherapy. In the real time tumour tracking treatment scheme, MR images are acquired in real time, then the tumour target is localized...

Fall 2011
The integration of a clinical linear accelerator (linac) with a magnetic resonance imager (MRI) will offer real time images during treatment, making tumor tracking possible. One of the challenges of the integration is removing any mutual interference between the two systems. Methods of removing...

Metal Artifact Reduction in Computed Tomographic (CT) Images for Radiotherapy Treatment Planning
DownloadSpring 2014
High density/high atomic number metallic objects create shading and streaking metal artifacts in the CT image that can cause inaccurate delineation of anatomical structures or inaccurate radiation dose calculation. We developed techniques for reducing metal artifacts in both megavoltage CT...

Spring 2010
Megavoltage computed tomography (MVCT) and megavoltage cone beam computed tomography can be used for visualizing anatomical structures prior to radiation therapy treatments to assist in patient setup and target localization. These systems provide images using the same beam used for patient...

External beam radiotherapy (EBRT) utilizes high energy radiation (primarily photons or electrons) generated from a linear accelerator (linac) for the treatment of cancer. Current linac technologies lack the ability to continuously monitor the tumour and surround area during treatment. Real-time...

The aim of this work is to evaluate the feasibility of low field MR based real time lung tumour tracking, a promising application of proposed linac-MR system. In this work, motion phantoms replicating low field MR contrast parameters for thoracic anatomy of lung cancer patients are imaged with...
