Ultrasound treatment device

Patent Pending The purpose of the present invention is to reduce as much as possible the projection of ultrasound other than on a treatment site. When a user designates a treatment range on a diagnostic image, a switch apparatus (12) selects a transmitter apparatus for treatment (16). Intense ultrasound for treatment is transmitted thereby from a probe (10) within an organism. When the treatment operation continues for a prescribed time, a control unit (18) controls the switch apparatus (12) and selects a transmitter apparatus for diagnosis (14).
