High-Volume-Rate Ultrasound for Quantitative Assessments of Vascular Function
(University of Waterloo, 2023-12-12)Free flap surgery is a common reconstructive technique to repair tissue damage after trauma or cancer removal. This complex procedure involves the transfer of tissue, along with its associated blood supply, from one ... -
Performance Evaluation of Passive Cavitation Mapping for Estimating Ultrasound-Induced Cavitation Dose
(University of Waterloo, 2023-11-28)The development of targeted drug delivery technologies to increase the specificity and efficacy of cancer treatments and reduce the reliance on systemic chemotherapy drugs have long been areas of research. Recent advances ... -
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 ... -
Receiver Channel Recovery in High-Frame-Rate Ultrasound Imaging using Branched Convolutional Neural Networks
(University of Waterloo, 2022-08-22)High frame rate ultrasound (HiFRUS) is an imaging paradigm that utilizes unfocused transmissions to perform acquisitions at kilohertz frame rates, and its high temporal resolution enables its use in tracking dynamic ... -
Robust Eigen-Filter Design for Ultrasound Flow Imaging Using a Multivariate Clustering
(University of Waterloo, 2020-01-23)Blood flow visualization is a challenging task in the presence of tissue motion. Unsuppressed tissue clutter produces flashing artefacts in ultrasound flow imaging which hampers blood flow detection by dominating part of ... -
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, ... -
Time-Resolved Wall Shear Rate Mapping using High-Frame-Rate Ultrasound
(University of Waterloo, 2018-06-19)Arterial wall shear rate is known to be strongly associated with plaque formation and stroke risk. As a non-invasive, point-of-care imaging modality, ultrasound has been applied to perform wall shear rate (WSR) measurements. ... -
Ultrasound Imaging Innovations for Visualization and Quantification of Vascular Biomarkers
(University of Waterloo, 2019-09-03)The existence of plaque in the carotid arteries, which provide circulation to the brain, is a known risk for stroke and dementia. Alas, this risk factor is present in 25% of the adult population. Proper assessment of carotid ... -
Ultrasound-Induced Cavitation for Controlled Drug Release from Thermosensitive Liposomes
(University of Waterloo, 2022-05-02)Ultrasound-induced cavitation of microbubbles has increased anticancer drug Doxorubicin (DOX) release from thermosensitive liposomes (TSL). Yet, the influence of liposomal formulations and their responses toward cavitation ...
