Title: A Method for Examining a Patient by Means of Ultrasonic Waves
IPC: A61B8/08
Filed: 1979-10-17
Abstract: In examining a patient, a first emitter-receiver system (1) comprising a plurality of elements controlled in phase emits a fan- shaped pattern of elementary ultrasonic beams, and a two- dimensional fan-shaped image of a section of the patient's body is produced in real time by a visualization device (5).
