The improvement of the accuracy of focusing was experimentally validated from the pressure measurement and the visualization of the focusing process. In addition, using this reflector expansion wave was irradiated to the bubble installed in the focusing region of the biological equivalent phantom. The behavior was visualized using an ultra high speed video camera.英語フィールド
