Abstract
Ultrasonic diagnosis apparatus including a plurality of transducer elements in a probe actuated by electric pulses for emitting ultrasonic pulses, for receiving echo ultrasonic pulses, and for issuing electric pulses corresponding to the echo pulses; a pulse generator; apparatus for processing the electric pulse information issued by the probe; a photo transmission line interconnecting the pulse generator and the probe and interconnecting the probe and the processing apparatus; and devices for converting electric pulses to photo pulses for conveyance on the photo transmission line and devices for reconverting the photo pulses to electric pulses after conveyance on the photo transmission lines are utilized with M number of multiplexers. Each multiplexer has L number of taps to drive N number of transducer elements where N=M.times.L. A preprogrammed controller sequences the actuation of the transducer elements such that M number of transducer elements are actuated for each electric pulse generated by the generator.
