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...

Multiple Sclerosis (MS) is a chronic neurodegenerative disease which is mainly characterized by inflammation, demyelination, and axonal loss. Conventional Magnetic Resonance Imaging (MRI) has become the most established imaging tool in the diagnosis and follow-up of MS in clinical practice....

Magnetic resonance imaging (MRI) is a valuable medical diagnostic technique due to its exceptional soft tissue contrast. Unfortunately, standard clinical MRI systems have limited accessibility worldwide, especially in developing countries, due to high costs, high weight, large physical...

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...

Arterial spin labeling (ASL) is a magnetic resonance imaging (MRI) noninvasive method, capable of measuring perfusion, i.e. blood flow, with blood as an intrinsic contrast. ASL measurements of cerebral perfusion are usually acquired at very low spatial resolution (> 60mm3 voxels), for several...

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...

The invention of magnetic resonance imaging (MRI) has advanced the diagnosis of diseases dramatically as it is capable of producing high-quality images of soft tissues non-invasively and safely. However, the high volume of MRI images also means heavy workloads for physicians, which results in...

Amyotrophic lateral sclerosis (ALS) is a highly heterogeneous disease in terms of its clinical presentation, progression, and detected pathology in the body. It is a multi-system degenerative disorder, though a diagnosis is made based on the presence of both upper motor neuron (UMN) and lower...

Deformable registration of cardiac magnetic resonance imaging (MRI) is one of the crucial tasks in medical image analysis. It aims to find the unique transformation between images taken from the same scene at different times, from different views, and by different imaging modalities such as MRI...

Diffusion magnetic resonance imaging (dMRI) measures the diffusion (i.e. random molecular motion) of water. Since the motion of water is inhibited by cellular membranes, dMRI provides insight into the microstructural characteristics of the tissue. However, distinguishing between small anatomical...
