An Automated Malignant Tumour Localization Algorithm for Prostate Cancer Detection in Trans-rectal Ultrasound Images
(University of Waterloo, 2004)The goal of this thesis is to design, implement and evaluate an automated algorithm to detect cancerous tissues and segment the malignant tumour in ultrasound images of the prostate. To accomplish this goal, first, the ... -
High-Frame-Rate Ultrasound Imaging Innovations for Complex Flow Quantification
(University of Waterloo, 2021-09-07)Vascular pathology such as atherosclerosis or arterial stiffening involves significant disruption in the blood flow dynamics found in the vasculature, with complex behavior such as jets and swirling typically seen in ... -
A Multi-scale Stochastic Filter Based Approach to Inverse Scattering for 3D Ultrasound Soft Tissue Characterization
(University of Waterloo, 2009-10-30)The goal of this research is to achieve accurate characterization of multi-layered soft tissues in three dimensions using focused ultrasound. The characterization of the acoustic parameters of each tissue layer is formulated ... -
Pressure Wave Velocity Using High-Frame-Rate Ultrasound Imaging for Urodynamic Study
(University of Waterloo, 2023-01-16)Benign Prostatic Hyperplasia (BPH) is a noncancerous urologic condition in aging males where an overgrowth of the prostate gland occurs. It notably leads to lower urinary tract symptoms ranging from inconvenient nocturia ... -
Robust Flow Component Identification for Blockwise SVD Clutter Filtering in High-Frame-Rate Ultrasound Using a Deeply Connected Neural Network
(University of Waterloo, 2023-01-10)Ultrasound plays a critical role in the accurate and reliable observation of blood flow dynamics within the human body and is instrumental in the assessment of cardiovascular health and subsequent follow-up treatment. ... -
Robust Sonographic Muscle Quality Assessment: A Live, Accurate Tissue Speed-of-Sound Estimation Framework
(University of Waterloo, 2024-02-23)Muscle quality can act as an indicator for physical health through qualitative – yet measurable – changes in muscle architecture and composition. One option for assessing muscle quality is through musculoskeletal ultrasound, ... -
Segmentation of 3D Carotid Ultrasound Images Using Weak Geometric Priors
(University of Waterloo, 2010-10-29)Vascular diseases are among the leading causes of death in Canada and around the globe. A major underlying cause of most such medical conditions is atherosclerosis, a gradual accumulation of plaque on the walls of blood ... -
Speckle Noise Reduction via Homomorphic Elliptical Threshold Rotations in the Complex Wavelet Domain
(University of Waterloo, 2005)Many clinicians regard speckle noise as an undesirable artifact in ultrasound images masking the underlying pathology within a patient. Speckle noise is a random interference pattern formed by coherent radiation in a ...
