Patent ID: 8579817

Claim:
A breast ultrasonic diagnostic apparatus for generating image data of an image of an examination-target portion based on volume data generated through an ultrasonic scan of an object and for displaying the image, the ultrasonic diagnostic apparatus comprising: a curved surface generating unit configured to generate, on the basis of the volume data, a curved surface formed to avoid a thorax, wherein the generated curved surface is a curved plane generated to avoid the thorax, but passes through a breast of the object, wherein the curved surface generating unit includes a curved line calculating unit configured to calculate a curved line on a first section that includes the breast based on a thorax line on the first section; and a curved surface calculating unit configured to calculate the curved surface based on the curved line determined by the curved line calculating unit; and a curved image generating unit configured to generate image data of a curved image based on data of the curved surface generated by the curved surface generating unit, wherein the curved surface calculating unit is configured to calculate the curved surface formed by moving the curved line, determined by the curved line calculating unit, in a direction orthogonal to the first section.
