Simultaneous Acoustic Radiation Force Imaging and PRFS Thermal Monitoring at 3 T for MRgHIFU focusing

Abstract

Introduction One challenge in MRgHIFU is to provide safe and thermally neutral focusing of HIFU beam pattern using acoustic radiation force imaging (ARFI). The radiation force is localized and highly directional (along the main propagation axis of the HIFU beam) while negligible outside the focal zone. This force initiates a tissue displacement correlated… (More)
