Radiation-force-based elasticity imaging describes a group of techniques that use acoustic radiation force (ARF) to displace tissue in order to obtain qualitative or quantitative measurements of tissue properties. Because ARF-induced displacements ar

Acoustic clutter produced by off-axis and multipath scattering is known to cause image degradation, and in some cases these sources may be the prime determinants of in vivo image quality. We have previously shown some success addressing these sources

An imaging technique that provides visual feedback of radiofrequency ablation (RFA) completeness could potentially increase the efficacy of transcatheter cardiac ablation (TCA) procedures for the treatment of cardiac arrhythmias.1 At lethal RFA tempe

A method for reliable, noninvasive estimation of abdominal aortic aneurysms (AAA) wall mechanics may be a useful clinical tool for rupture prediction. An in vitro AAA model was developed from an excised porcine aorta with elastase treatment. The AAA

In traditional shear wave elasticity imaging (SWEI), shear wave velocity is measured away from the acoustic radiation force (ARF) axis. Instead, we measure the time-to-peak displacement of tissue directly along the ARF axis. Measuring displacements a
