Abstract: An ultrasonic scanning pulse-generating apparatus includes a rotary encoder for outputting a pulse every time a motor, driving an ultrasonic transducer, rotates through a predetermined angle, and a pulse cycle-measuring circuit for measuring the one-cycle period of pulses output from the rotary encoder. An address pulse output circuit is provided for outputting a pulse during each of the periods defined by dividing the one-cycle period by a predetermined number m. The address pulse output circuit is connected to a scanning pulse-generator including an address-forming circuit for constructing address data from the address pulse obtained by the address pulse output circuit, and a memory storing scanning pulse data and addressed by the address data of the address-forming circuit, to output a scanning pulse.

Abstract: An ultrasonic reception signal from a subject being examined is detected by use of an ultrasonic image recording system. Of the ultrasonic images obtained by means of image processing, only image data required for display purposes is recorded in the system. Through the simultaneous superimposition of recorded ultrasonic image data and ultrasonic scanning condition data on a superimposing circuit, these two data are recorded on the same recording area at a line scan recorder.
