Capacitive Micromachined Ultrasonic Transducers for Non-destructive Testing Applications
(University of Waterloo, 2014-08-07)Ultrasound is a popular technique for industrial non-destructive testing (NDT) applications. By sending ultrasonic waves into an object and observing the amplitude and the delay of the reflected or transmitted waves, one ... -
Characterizing site-specific body composition of older adults and their associations with strength, functional capacity, and metabolic health
(University of Waterloo, 2021-06-03)Background: Ageing is associated with skeletal muscle atrophy and increased intramuscular adipose tissue. Emerging evidence indicates that specific muscle groups may be largely responsible for the ageing-related degradation ... -
The Design, Fabrication and Characterization of Capacitive Micromachined Ultrasonic Transducers for Imaging Applications
(University of Waterloo, 2010-10-01)Capacitive micromachined ultrasonic transducers (CMUTs) have proven themselves to be excellent candidates for medical ultrasonic imaging applications. The use of semiconductor fabrication techniques facilitates the fabrication ... -
Development of a Feasible Elastography Framework for Portable Ultrasound
(University of Waterloo, 2017-10-06)Portable wireless ultrasound is emerging as a new ultrasound device due to the advantages such as small size, lightweight and affordable price. Its high portability allows practitioners to make diagnostic and therapeutic ... -
Factors Influencing Measures of Trochanteric Soft Tissue Thickness
(University of Waterloo, 2016-09-02)Introduction: Trochanteric soft tissue thickness (TSTT), which attenuates the force applied to the hip upon impact, has emerged as a potential factor that may improve the assessment of the risk of a hip fracture. However, ... -
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 ... -
Prostate Segmentation and Regions of Interest Detection in Transrectal Ultrasound Images
(University of Waterloo, 2007-09-21)The early detection of prostate cancer plays a significant role in the success of treatment and outcome. To detect prostate cancer, imaging modalities such as TransRectal UltraSound (TRUS) and Magnetic Resonance Imaging ... -
Variations on Acoustophoretic Microchannels: From the Facile to the Highly Capable
(University of Waterloo, 2018-05-31)The lab-on-a-chip toolkit is replete with techniques for microparticle manipulation. The use of ultrasonic waves to impart forces on particles, referred to as acoustophoresis, is one particularly powerful yet gentle option. ... -
Wave Refraction Effects in High Intensity Focused Ultrasound
(University of Waterloo, 2019-01-22)High-Intensity Focused Ultrasound (HIFU) is a promising field of research being developed as an alternative to surgery and radiation therapy for the treatment of tumours. Within this field, many current methods of ...
