ABSTRACT:
In a shock wave therapy apparatus, shock wave irradiation conditions, such as the number of shock wave irradiations, a pulse rate, a driving voltage, and the number of pause shots, are set by a setting unit in accordance with the position and size of a calculus in a subject which are acquired by an ultrasonic tomographic image. Irradiation of shock waves by a shock wave applicator starts according to the set shock wave irradiation conditions, and the ultrasonic tomographic image and the corresponding irradiation condition data are displayed on a display unit during shock wave irradiation. When the number of shock wave irradiations reaches the number of pause shots, the shock wave irradiation is temporarily stopped. Then, the focus point of a shock wave is moved on the basis of the ultrasonic tomographic image and irradiation condition data displayed on the display unit. When the shock wave irradiation is completed, a therapy record of the subject is printed out by an output unit.
