ABSTRACT:
In an ultrasound therapeutic system provided with an ultrasound transmitter having a focusing mechanism and a plurality of groups of ultrasound transmitters/receivers, each of which has a controllable directivity, each of the transmitters/receivers is constructed so as to be able to receive both echo of pulse-shaped ultrasound transmitted by itself and even order harmonic signals of the ultrasound transmitted by the transmitter, and a plurality of two-dimensional pulse echographical images constructed by ultrasound signals obtained by transmitting/receiving beams, while controlling the directivity of the beam emitted by each of the plurality of groups of ultrasound transmitters/receivers and a plurality of images indicating orientation and intensity, in which an even order harmonic wave signal due to the ultrasound transmitted by the transmitter is received by each of the plurality of groups of ultrasound transmitters/receivers, are displayed, superimposed on each other.
