The Application of FROID in MR Image Reconstruction
(University of Waterloo, 2010-05-21)In magnetic resonance imaging (MRI), sampling methods that lead to incomplete data coverage of k-space are used to accelerate imaging and reduce overall scan time. Non-Cartesian sampling trajectories such as radial, spiral, ... -
Design and Implementation of Calculated Readout by Spectral Parallelism (CRISP) in Magnetic Resonance Imaging (MRI)
(University of Waterloo, 2010-05-20)CRISP is a data acquisition and image reconstruction technique that offers theoretical increases in signal-to-noise ratio (SNR) and dynamic range over traditional methods in magnetic resonance imaging (MRI). The incoming ... -
HARDI Denoising using Non-local Means on the ℝ³ x 𝕊² Manifold
(University of Waterloo, 2012-01-05)Magnetic resonance imaging (MRI) has long become one of the most powerful and accurate tools of medical diagnostic imaging. Central to the diagnostic capabilities of MRI is the notion of contrast, which is determined by ... -
A HoloLens Framework for Augmented Reality Applications in Breast Cancer Surgery
(University of Waterloo, 2018-02-01)This project aims to support oncologic breast-conserving surgery by creating a platform for better surgical planning through the development of a framework that is capable of displaying a virtual model of the tumour(s) ... -
Information Fusion of Magnetic Resonance Images and Mammographic Scans for Improved Diagnostic Management of Breast Cancer
(University of Waterloo, 2021-08-27)Medical imaging is critical to non-invasive diagnosis and treatment of a wide spectrum of medical conditions. However, different modalities of medical imaging employ/apply di erent contrast mechanisms and, consequently, ... -
Spatially Regularized Reconstruction of Fibre Orientation Distributions in the Presence of Isotropic Diffusion
(University of Waterloo, 2014-04-14)The connectivity and structural integrity of the white matter of the brain is known to be implicated in a wide range of brain-related diseases and injuries. However, it is only since the advent of diffusion magnetic resonance ... -
Spatially Regularized Spherical Reconstruction: A Cross-Domain Filtering Approach for HARDI Signals
(University of Waterloo, 2013-09-03)Despite the immense advances of science and medicine in recent years, several aspects regarding the physiology and the anatomy of the human brain are yet to be discovered and understood. A particularly challenging area in ...
