Being an emerging body-shaping technology of fat cell disruption, high-intensity focused ultrasound has been investigated intensively in recent years for its favorable natures such as painlessness, safety and noninvasion. One of the major problems for the technology, however, is the overheating of transducers. In this study, we modified the transducer design in order to solve the overheating problem. We simulated the performance of the modified design by finite element analysis and fabricated the newly designed transducer. By measuring the actual performance data, we proved that the new design can effectively reduce temperature rise while keeping the acoustic intensity field unaffected.
