Hippocampal Diffusion Tensor Imaging in Parkinson's Disease and Associations with Non- Motor Symptoms
DownloadSpring 2023
Parkinson’s disease (PD) is the second most common neurodegenerative disorder and causes not only well-characterised motor symptoms, but also a host of non-motor symptoms that greatly impact quality of life. PD exists within a larger spectrum of disorders caused by the accumulation of Lewy bodies...

STRUCTURAL AND METABOLIC MRI TO CHARACTERIZE THE RESPONSE TO SURGERY IN TRIGEMINAL NEURALGIA
DownloadSpring 2023
Trigeminal Neuralgia (TN) is a chronic, neuropathic, facial pain condition characterized by severe unilateral pain attacks, electric shock-like or shooting in character, confined to regions of the face innervated by the trigeminal nerve (the fifth cranial nerve, CNV). TN is commonly associated...

Quantitative Susceptibility Mapping in Human Brain: Short Echo Timing, Thin Slab, and Non-harmonized Multisite Applications
DownloadSpring 2023
Quantifying tissue magnetic susceptibility provides a non-invasive way to monitor iron and myelin abnormalities associated with several neurodegenerative diseases. Quantitative susceptibility mapping (QSM) is a post-processing technique that retrieves the susceptibility distribution from the...

Time Domain Principal Component Analysis for Rapid, Real-Time 2D MRI Reconstruction from Undersampled Data
DownloadSpring 2022
Hybrid Linac-MR systems are becoming more mainstream for use in external beam radiotherapy treatments for cancer patients. The addition of an MR scanner to a linear accelerator (Linac) can allow for real-time structure tracking (such as a tumour) and on-the-fly adjustments of the radiation beam....

V-CoHOG: Volumetric Co-occurrence Histograms of Oriented Gradients for Texture Classification in Medical Imaging
DownloadFall 2022
Image textures, which are properties that can describe the pixel intensities of an image, have been analyzed in order to perform a variety of tasks, including segmentation and classification. Features derived from textures which are invariant to changes such as contrast and transformations are of...

Advances in Quantitative Susceptibility Mapping for Human Brain: Applications in Hemorrhage, Motion, Blood Vessels
DownloadFall 2022
Quantitative Susceptibility Mapping (QSM) is an emerging postprocessing method, computed from phase images, which is finding wide application in quantifying iron content in healthy and pathological tissue. However, QSM is still not commonly used in clinical practice. This thesis discusses the...

A Diffeomorphic 3D-to-3D Registration Algorithm for the Segmentation of the Left Ventricle in Ultrasound Sequences
DownloadFall 2021
Heart disease is the second leading cause of death in Canada, where it affects the lives of over two million people. One modality used to detect and diagnose heart disease and other abnormalities is echocardiography or ultrasound imaging of the heart. Ultrasound imaging, compared to other...
