| 摘要 |
According to the present invention, a therapeutic probe 1 includes a diagnostic probe 2, a therapeutic transducer 3, and a supporting member for supporting them, wherein the therapeutic transducer has a plurality of transducer elements, and a focal point at which ultrasonic waves transmitted by the respective transducer elements converge can be freely shifted by controlling the timing of supplying driving signals to the respective transducer elements. By locating the focal point of ultrasonic beams of the therapeutic transducer 3 on the plane scanned by ultrasonic beams of the diagnostic probe 2, the ultrasonic therapy can be performed while substantially observing the portion to be treated through the diagnostic image.
