A 3-D Multiparametric Ultrasound Elasticity Imaging System for Targeted Prostate Biopsy Guidance
(2023)Prostate cancer is the most common cancer and second-leading cause of cancer death among men in the United States. Early and accurate diagnosis of prostate cancer remains challenging; following an abnormal rectal exam or ... -
Acoustic Radiation Force Impulse-Driven Shear Wave Velocimetry in Cardiac Tissue
(2010)Acoustic radiation force impulses (ARFI) have been used to generated transverse-traveling mechanical waves in various biological tissues. The velocity of these waves is related to a medium's stiffness and thus can offer ... -
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 ... -
Mapping Myocardial Elasticity with Intracardiac Acoustic Radiation Force Impulse Methods
(2014)Implemented on an intracardiac echocardiography transducer, acoustic radiation force methods may provide a useful means of characterizing the heart's elastic properties. Elasticity imaging may be of benefit for diagnosis ... -
Multi-Dimensional Ultrasonic Shear Wave Reconstructions: Improving the Accuracy of Viscoelastic Parameter Estimation
(2018)Hepatocellular carcinoma (HCC) lesions are often preceded by liver cirrhosis or Hepatitis C, and patients with these diagnoses are monitored every six months with an ultrasound screening. B-mode ultrasound is an ideal imaging ... -
Transthoracic Measurement of Dynamic Myocardial Stiffness using Acoustic Radiation Force-Based Ultrasound Methods
(2018)Heart failure is one of the most common cardiac disorders and is projected to increase in prevalence over the next few decades. It can arise from a wide variety of root causes such as coronary artery disease, hypertension, ...
