1. An ultrasonic diagnostic apparatus comprising:
- an ultrasonic probe including a plurality of transducers;
a transmission unit configured to transmit ultrasonic waves to a scanning target region in a subject via the plurality of transducers;
a reception unit configured to receive ultrasonic waves from the scanning target region via the plurality of transducers;
a volume data generation unit configured to generate volume data concerning the scanning target region based on a reception signal from the reception unit;
a region-of-interest setting unit configured to set a predetermined range in the volume data to a region of interest, the predetermined range having a central axis coinciding with a planned insertion route of a puncture needle;
an expansion image generation unit configured to generate an expansion image expressing a brightness distribution on a side surface of the region of interest in the volume data by two-dimensional polar coordinates defined by a rotational angle around the central axis and a distance from a reference point on the central axis; and
a display unit configured to display the expansion image.

Abstract
According to one embodiment, an insertion area setting unit sets an insertion area in a predetermined range with a planned insertion route of a puncture needle in volume data being a central axis. An expansion image generation unit generates an expansion image expressing a brightness distribution on a side surface of the insertion area in the volume data by two-dimensional polar coordinates defined by a rotational angle around the central axis and a distance from a reference point on the central axis. A display unit displays the expansion image.
