Simulation, design and implementation of external mechanical vibration for shear wave elastography imaging (original) (raw)

2017 IEEE International Ultrasonics Symposium (IUS), 2017

Abstract

Ultrasound shear wave elastography (SWE) imaging is commercially available on expensive systems. ARF-based shear wave generation requires complex electronics and may induce thermal stress to the tissue. There is need and interest to develop external mechanical vibration (EMV) as a low-cost approach to generate shear waves. Commercial development of mechanical vibration using a single-element transducer has been successful but lacks 2D imaging as guidance. Here we present the simulation, design and implementation of a new way of performing external mechanical vibration that could be adopted by commercial ultrasound probes for SWE imaging.
