Ultrasound therapeutic apparatus

摘要

An ultrasonic therapeutic apparatus consisting of a therapeutic ultrasonic wave generating source (2) is driven by a driver circuit (14) to generate therapeutic ultrasonic waves, an in vivo imaging probe (16) so as to obtain a tomographic image in the vicinity of the focus of the therapeutic ultrasonic waves. The imaging probe (16) is used to receive echoes of the ultrasonic pulses emitted from therapeutic ultrasonic wave generating source. The driving conditions for the therapeutic ultrasonic wave generating source (2) is adjusted on the basis of a received echo signal. The received echo signal contains information about actual intensity of the therapeutic ultrasonic waves within a living body, thus improving the safety and reliability of therapy.
