Abstract
Abstract In an ultrasound treatment apparatus comprising a power transducer in the form of a spherical dish (1) both as generator of the treatment waves and as echographic emitter-receiver, the transducer is caused to oscillate (motor 2) during the period of the treatment, in order to obtain a sectoral scanning of type B, and excitation thereof takes place (circuits 1 to 14) with treatment waves only within a restricted angular sector of the scanning and with echographic waves within the remainder of the scanned sector. <IMAGE>
