Abstract:
An ultrasonic therapeutic apparatus comprising:a source of therapeutic ultrasonic waves;an ultrasonic probe;means for driving said source of therapeutic ultrasonic waves;means for driving said ultrasonic probe to generate imaging ultrasonic waves;receiving means for receiving echoes of first ultrasonic waves generated by said therapeutic ultrasonic wave generating source and echoes of second ultrasonic waves generated by said ultrasonic probe through said ultrasonic probe;first filtering means for extracting a first component within a first specific band corresponding to the fundamental frequency of said first ultrasonic waves from an output of said receiving means;second filtering means for extracting a second component within a specific band corresponding to the fundamental frequency of said second ultrasonic waves from said output of said receiving means;means for amplifying each of said first and second components individually; andmeans for forming an image on the basis of said first and second components amplified by said amplifying means.
