Abstract
Ultrasonic treatment equipment is provided which repeats therapeutic ultrasound exposure while measuring a degree of vessel constriction on a therapeutic ultrasound exposure basis. This equipment includes: a therapeutic ultrasonic transducerwhich exposes a blood vessel of an affected part to a focused therapeutic ultrasonic wave for a specified period of exposure time; an imaging ultrasonic probewhich images an ultrasound tomographic image of the affected part; a display unitwhich displays the ultrasound tomographic image; meansfor detecting a blood flow signal from a signal received by the imaging ultrasonic probe and determining the blood flow velocity of the blood vessels of the affected part; meansfor calculating a rate of change in blood flow velocity during the exposure to the therapeutic ultrasonic wave or before and after the exposure to the therapeutic ultrasonic wave; and meansfor controlling exposure conditions of the therapeutic ultrasonic wave on the basis of the rate of change in blood flow velocity, and thereby controlling the therapeutic ultrasonic transducer.
