Assessment of Cardiac Function by Acoustic Radiation Force (ARF) Based Methods of Ultrasound Elastography
(2017)Heart Failure (HF) is a major cause of morbidity and mortality in the world. This disorder is characterized by compromised systolic and/or diastolic function of the myocardium that reduces the pumping and/or filling efficiency ... -
Assessment of Mechanical and Hemodynamic Vascular Properties using Radiation-Force Driven Methods
(2011)Several groups have proposed classifying atherosclerotic disease by using acoustic radiationforce (ARF) elasticity methods to estimate the mechanical and materialproperties of plaque. However, recent evidence suggests that ... -
Chronic Myocardial Infarct Visualization Using 3D Ultrasound
(2011)This dissertation aims to demonstrate the feasibility of direct infarct visualization using 3D medical ultrasound. The dissertation proceeds by providing the first ever demonstration of fully-sampled 3D ultrasonic speckle ... -
Comparison of Acoustic Radiation Force Impulse (ARFI) Imaging and Shear Wave Imaging (SWI) in Evaluation of Myocardial Ablation Lesions
(2013)Radiofrequency ablation (RFA) is commonly used to treat cardiac arrhythmias, by generating a series of discrete RFA lesions in the myocardium to isolate arrhythmogenic conduction pathways. The size of each lesion is controlled ...
