When a user designates a treatment range on a diagnostic image, a switch (12) selects a transmitter for treatment (16). Ultrasound with intensity for treatment is thereby transmitted from a probe (10) to the inside of an organism. When the treatment operation continues for a prescribed time, a control unit (18) controls the switch (12) to select a transmitter 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 a positional shift of the site to be treated. In the inspection, the control unit (18) compares the diagnostic image with a reference image, and if a significant difference is detected therebetween, determines that a shift has occurred, issues an alarm, and urges the user to correct the positional shift. It is possible to resume the treatment when the positional shift has been corrected.
