ULTRASOUND TREATMENT DEVICE AND CONTROL METHOD THEREOF

摘要

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). The probe (10) thereby emits an ultrasound beam for diagnosis, senses an echo thereof, generates a diagnostic image, and carries out an inspection of positional deviation of the site to be treated. In the inspection, the control unit (18) compares the diagnostic image with a reference image (i.e., a diagnostic image taken either when the treatment range is specified or when an inspection immediately prior to treatment is carried out), and if a significant difference is detected therebetween, determines that a deviation has occurred, issues an alarm, and calls on the user to correct the positional deviation. It will be possible to resume the treatment when the positional deviation has been corrected.
