[Flexible ultrasonic echo-probes and the prospects for their use in oncological practice].

Medico-technical requirements for a flexible echo-probe that can be connected to the Soviet-made ultrasonic diagnostic devices of the uda-724, uda-871, ékho-aa, ékho-12 types etc, were laid down. A mock-up of a flexible echo-probe, based on the electrical scanning by an ultrasonic beam was constructed. The use of flexible echo-probes broadens the possibilities for the ultrasonic investigations of tumours in the esophagus, stomach and rectum in the oncological practice.
