Patent ID: 8382669

Claim:
An ultrasonic diagnostic apparatus which generates volume data on the basis of ultrasound data collected by transmitting/receiving ultrasonic waves to/from a three-dimensional region of a specimen, and displays, in real time, image data obtained by processing the volume data, the apparatus comprising: a scan unit which scans the three-dimensional region by transmitting ultrasonic waves to the three-dimensional region and receiving ultrasonic waves from the three-dimensional region; a control unit which controls the scan unit so as to perform a first scanning of a first arrangement for a number of slices and a second scanning, the second scanning being performed with a first arrangement for a number of slices higher than the first scanning; a gain correction data generating unit which generates three-dimensional gain correction data for the volume data on the basis of the received ultrasonic waves in the first scanning; and a gain setting unit which sets, on the basis of the gain correction data, a gain of at least one of signals based on the received ultrasonic waves obtained by the second scanning.
