Patent ID: 7699779

Claim:
An ultrasonic treatment equipment comprising: a therapeutic ultrasonic transducer which exposes a blood vessel of an affected part to a focused therapeutic ultrasonic wave for a specified period of exposure time; an imaging ultrasonic probe which images an ultrasound tomographic image of the affected part; a display unit which displays the ultrasound tomographic image; means for comparing a blood flow velocity of the blood vessel before the exposure to the therapeutic ultrasonic wave with that after the exposure to the therapeutic ultrasonic wave, and calculating a rate of change in blood flow velocity; and a control unit for controlling the exposure to the therapeutic ultrasonic wave based on the rate of change in blood flow velocity for causing the blood vessel of the affected part to be constricted or become infracted, wherein if the rate of change in blood flow velocity before and after the exposure to the therapeutic ultrasonic wave is within a range of a predetermined rate of change, the control unit repeats the exposure to the therapeutic ultrasonic wave, whereas if the rate of change in blood flow velocity before and after the exposure to the therapeutic ultrasonic wave is out of the range of the predetermined rate of change, the control unit ends the exposure to the therapeutic ultrasonic wave.
