2P5-9 Distribution of temperature elevation caused by moving HIFU transducer(Poster Session)

Abstract

In this study, in order to examine the heat stimulus caused by HIFU transducer for dermatology on human tissue, the temperature elevation in the tissue mimicking phantom was visualized when the ultrasound was radiated while a small sized HIFU transducer moved on the surface of the phantom. As the results, the temperature elevation degree and range could be obtained for different acoustic energy and moving interval when the HIFU transducer moved on linear path. Using suggested method, the accumulated thermal energy distribution in human tissue caused by ultrasound can be estimated non-invasively, and it would provide important information to design the transducer and to estimate remedial value.
