Abstract

One of the weaknesses in USgHIFU is the limited accuracy and sensitivity of the ultrasonic imaging, which is often contaminated by strong HIFU waves. The focal position is considered as the essential parameter since all treatments are planned spatially according to it; however, focal position can be affected by the heterogeneous structures and textures of the medium. This research proposal describes an imaging method named the rapid passive acoustic mapping that permits indication of the actual focal point with a short HIFU pulse and linear array probe, which can be embedded into a diagnostic ultrasound system compatible with HIFU.
