Abstract

The purpose of the present invention is to evaluate the influence of ultrasonic waves transmitted from a therapeutic ultrasonic transducer by an ultrasonic imaging probe. The control unit (22) executes an ultrasonic wave transmission process, an ultrasonic wave reception process, and a distribution measurement process. The ultrasonic wave transmission process is a process for transmitting an evaluation ultrasonic wave having a lower intensity than the therapeutic ultrasonic wave to the therapeutic ultrasonic transducer (14). The ultrasonic wave reception process is a process for acquiring, from each of the transducers (28), a reception signal based on the ultrasonic waves received by each of the transducers (28). The distribution measurement process is a process for measuring the intensity distribution of the ultrasonic waves reaching the plurality of transducers (28) on the basis of the reception signals acquired from the respective transducers (28).
