ACOUSTIC COMPUTER MAMMOGRAPH WITH THREE DIMENSIONAL VISUALIZATION Russian patent published in 1999 - IPC

Abstract RU 2139679 C1

FIELD: medical ultrasonic diagnostic equipment. SUBSTANCE: mammograph is intended for examination and early diagnostics of mammary gland diseases. Mammograph has ultrasonic transducer including step motor with reduction gear, shaft of which carries piezoelectric transducer module with acoustic lens. Mammograph also includes low-noise amplifier, analog-to- digital converter, buffer main storage, computer, processor, and monitor, as well as step-motor control unit, clock-pulse generator, and programmed controller. In addition, mammograph has unit of sounding signal and control signal formation, M/2 removal delay line, cyclic switch, two M-channel "receive-transmit" switches, multiplexer, M-channel power amplifier, M-channel low- noise amplifier, as well as user's interface having interactive connection with monitor, and synthesis parameter control unit. EFFECT: high resolution. 4 cl, 6 dwg
