Patent ID: 8652049

Claim:
An ultrasonic diagnostic apparatus comprising: an ultrasonic probe; an ultrasonic transmission/reception unit configured to repeatedly transmit/receive an ultrasonic wave N times for each of a plurality of ultrasonic rasters via the ultrasonic probe and generate a plurality of echo signals; an echo processing unit configured to generate complex data based on the echo signals; a phase shifting unit configured to shift a phase of each ensemble data constituted by N complex data associated with the same depth on the same ultrasonic raster in accordance with a reference phase; an interpolation processing unit configured to interpolate ensemble data associated with an interpolated raster between adjacent ultrasonic rasters based on the phase-shifted ensemble data; and an image data generation unit configured to generate image data based on the phase-shifted ensemble data and the interpolated ensemble data, wherein the phase shifting unit specifies an average of a phase difference between a phase of N/2th complex data of the ensemble data and the reference phase and a phase difference between a phase of ((N/2)+1)th complex data and the reference phase when the number N is an even number.
