Acoustic Radiation Force Impulse Imaging of Myocardial Performance
… myocardial performance is myocardial stiffness. Acoustic radiation force impulse (ARFI) imaging has been demonstrated to be capable of visualizing variations in local stiffness within soft tissue. </p><p>In this thesis, the initial investigations into the visualization of myocardial performance …

Volumetric Acoustic Radiation Force Impulse Imaging Using Intracardiac Echocardiography
… currently in use in the clinic have difficulties imaging face-on regions of myocardial tissue, requiring meticulous and time-consuming translational and rotational scanning of the array. This dissertation investigates the use of helicoid array transducers to perform ICE-based acoustic radiation …

Identifying Vulnerable Plaques with Acoustic Radiation Force Impulse Imaging
… dissertation evaluates the hypothesis that Acoustic Radiation Force Impulse (ARFI) imaging can noninvasively identify lipid regions, that have been shown to increase a plaque's propensity to rupture, within carotid artery plaques <italic>in vivo</italic>. The work detailed herein describes …

The Potential for Ultrasonic Image-Guided Therapy Using a Diagnostic System
… a diagnostic system can be used for combined imaging and therapeutic applications. In order to evaluate the effectiveness of a diagnostic system for use in therapeutic applications, a set of non-destructive tests is developed that can predict the potential for high acoustic output. A rigorous, …

The Mechanism of Action of Hyaluronan Therapy as a Treatment for Osteoarthritis and the Assessment of Osteoarthritic Articular Cartilage Using Ultrasound
… early and to treat effectively. Existing imaging techniques often only detect osteoarthritic damage after substantial structural loss has occurred. This thesis investigates two key aspects of OA management: (1) how hyaluronan (HA) therapy interacts with articular cartilage at the molecular …
