ULTRASONIC TREATMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To improve the safety and certainty of a treatment by receiving the echo of first ultrasonic waves from an ultrasonicwave-for-treatment generation source and the echo of second ultrasonic waves from an ultrasonic probe and constituting the intensity distribution of the ultrasonic waves for the treatment based on reception signals. SOLUTION: The ultrasonic waves for the intensity distribution are cyclically generated from the ultrasonic-wave-for-treatment generation source 2 in a band whose center is a first fundamental frequency and the echo of the ultrasonic waves for the intensity distribution is received by a probe 16 for imaging. The piezo element of the probe 16 for imaging is highly sensitive for both of the first fundamental frequency of the ultrasonic waves for the intensity distribution and the second fundamental frequency of the ultrasonic waves for imaging. Since the intensity distribution is imaged based on lower harmonic components largely included in the echo of the ultrasonic waves for the intensity distribution, the intensity distribution faithful to the actual intensity distribution is obtained and judgement such as the estimation or the like of a heat generation area or the like is highly accurately performed based on the intensity distribution.
