摘要： An ultrasonic diagnostic equipment of linear electric scanning type includes a plurality of pulse generators for supplying electric pulses to a plurality of ultrasonic transducers disposed on a plane, gate circuits for driving the pulse generator, a plurality of analogue switching circuits for selecting the reflected ultrasonic pulse signals received by the ultrasonic transducers, and a control circuit for controlling these pulse generators and switching circuits. The control circuit synchronizingly controls the operations of the gate circuits and analogue switching circuits in order to operate a given number of ultrasonic transducers of the plural of the ultrasonic transducers. The pulse generator and switching circuit are provided corresponding to each transducer.
