ABSTRACT:
An ultrasonic diagnosing apparatus comprising a probe for radiating ultrasonic wave beams toward a target and converting ultrasonic echo data reflected from the target into electrical signals indicative of a tomogram of the target, an ultrasonic wave transmission and reception circuit for controlling the probe to radiate the ultrasonic wave beams in predetermined ultrasonic field patterns, a processor for processing the electrical signals in accordance with correlations among the ultrasonic echo data, which depend upon the ultrasonic field patterns to eliminate artifact components of the tomogram from the electrical signals, a display device for displaying the tomogram of the target in response to the output signal of the processor, and a system pulse generator for generating a system synchronizing pulse supplied to the transmission and reception circuit and processor.
