Abstract
In one embodiment, an ultrasonic diagnostic apparatus includes a probe configured to be equipped with plural transducers arranged in a first direction and a second direction perpendicular to the first direction and be able to perform a two-dimensional scan in the first and second directions; a moving device configured to support the probe and mechanically move the probe in the second direction; a receiving circuit configured to generate first reception signals for respective moving positions of the probe in the second direction by performing receiving phase-compensation and summation processing on respective reflected signals received by the plurality of transducers at each of the moving positions; and processing circuitry configured to generate a second reception signal by performing moving aperture synthesis on the first reception signals generated for the respective moving positions of the probe based on positional information of the probe and generate image data from the second reception signal.
