Ultrasonic diagnostic apparatus

摘要

According to one embodiment, an ultrasonic diagnostic apparatus comprises an ultrasonic probe (2), an ultrasonic transmission/reception unit (3, 4), an echo processing unit (41) configured to generate complex data based on the echo signals, a phase shifting unit (43) 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 (5) 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 (7) configured to generate image data based on the phase-shifted ensemble data and the interpolated ensemble data.
