Ultrasonic device for examining and locating tumours provided with a device for localized hyperthermy treatment

摘要

device for treatment by hyperthermia.it is characterized in that a generator of a focused beam of ultrasound including a main transmitter (3) and a high frequency electric waves by piezoelectric transducerll (1) whose active surface is focalisante.an ultrasound system comprising an auxiliary generator for high frequency electrical pulses (211) with a piezo electric transducer (2) and the auxiliary means (20, 2001 - 4) result in a scan of the area to be treated by the ultrasound beam produced by the transducer (review; and switching means (210, 213 (33) and adjustment tocause for a primary mode of operation in the treatment and control.the issue of the focused beam by the main transducer excited by the main transmitter in periodic time intervals separated by time intervals smaller inthe issue of which beam of ultrasound images and the training is carried out.
