Ultrasonic immersion echomammography: state of the art and prospects.

This article discusses the state of the art and the prospects of evolution of ultrasonic immersion mammographs. It is shown that ultrasonic immersion mammography for diagnostics of surface organs has a preference over existing ultrasonic scanning devices of contact type. An immersion mammograph has been developed, a characteristic of which is the use of compact ring multielement antenna with the electronic dynamic focusing block.
