Background: Intracerebral Hemorrhage (ICH) is associated with high morbidity and patients commonly suffer motor dysfunction. ICH volume is a significant predictor of outcome, and perihematoma edema may also represent tissue injury. Diffusion Tensor Imaging (DTI) can be used to assess in-vivo...
Magnetic resonance imaging (MRI) is a valuable imaging modality and is commonplace in diagnosing, evaluating, and understanding the pathobiology of many neurological disorders. Current methods are helpful in the diagnosis of multiple sclerosis (MS) but fail to provide useful longitudinal...
Spinal cord injury is most commonly caused by physical trauma, and the resulting functional loss can vary considerably in both degree, extent and location. Understanding what spinal cord tissue is damaged and to what degree can be useful in both determining the appropriate treatment for...
A promising approach to the development of an integrated system for magnetic resonance imaging-guided radiotherapy involves the rigid coupling of a medical linear accelerator to a rotating biplanar magnet assembly. Through near real-time volumetric imaging during irradiation, this hybrid system...
Measurement and Correction for the Magnetic Susceptibility Effects of Fat in Venous Oximetry: Application in the Quantification of Muscle Oxygen Consumption (VO2) with Plantar Flexion ExerciseDownload
Measuring venous oxygen saturation (SvO2) provides direct assessment of the upstream muscle or organ's ability to extract and metabolize oxygen. Previously, measurement of venous oxygen saturation has been performed in most studies by intravenous catheterization. This approach has the advantage...
Magnetic resonance imaging (MRI) is a universally-used tool in clinical neurosurgery. It has revolutionized preoperative diagnosis, surgical planning, intraoperative targeting, and postoperative surveillance. Nevertheless, the idea that early, quantifiable perioperative structural changes of the...
Quantitative susceptibility mapping (QSM) is an emerging magnetic resonance imaging (MRI) method that provides image contrast based on an important underlying brain tissue property. It is derived from the phase images from a gradient echo sequence, and overcomes the orientation dependency problem...
In magnetic resonance imaging (MRI), radio frequency (RF) detectors or “coils” are used to excite and receive signal from the nuclear spins. This thesis focuses on the design and development of RF coils and methods to achieve the best possible image quality at high static magnetic field strengths...
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...
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...
