Abstract
Abstract At the bottom of a receptacle for medical examinations which is filled with warm water, there is an ultrasonic probe swinging along the bottom face for sector-shaped mechanical scanning and also for electronic scanning in a longitudinal direction at right angles to the mechanical scanning direction. Immersed in the warm water, an ultrasonic-wave transmitting flexible membrane is stretched across the receptacle above the ultrasonic probe. This membrane is provided with a plurality of pores through which the warm water passes. A breast to be examined is pressed against the membrane while it is immersed in the warm water, and a sectional image of the breast is displayed on a display unit by means of the ultrasonic probe.
