<p><P>PROBLEM TO BE SOLVED: To improve image resolution in an elevation direction with a simple structure without deteriorating an image obtaining speed in an ultrasonic apparatus for obtaining an ultrasonic image while continuously moving a probe in the elevation direction. <P>SOLUTION: Provided is the ultrasonic apparatus, including: a moving mechanism for moving a probe (1) in an elevation direction; a first phasing-adding circuit (9) for performing phasing and adding of reception signals (6) at individual positions along the elevation direction to output a first add signal (10); a signal extraction circuit (24) for letting an output of the phasing-adding circuit to pass through delay circuits (23a, 23b) to output in parallel first add signals obtained at different positions; a second phasing-adding circuit (27) for performing phasing and adding of the first add signals (a, b, c) output from the signal extraction circuit to output a second add signal; and an image processing circuit for generating image in a subject by using the second add signal. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
