Patent ID: 8540636

Claim:
An ultrasonic diagnostic apparatus comprising: an image generating unit configured to generate data of a plurality of ultrasonic images by repeatedly scanning a three-dimensional area including a heart of an object with ultrasonic waves; a short-axis image generating unit configured to generate a plurality of short-axis images intersecting a long cardiac axis from the ultrasonic images; an index calculating unit configured to calculate indices associated with a motor function of a cardiac wall from the short-axis image; a polar coordinate distribution generating unit configured to generate a polar coordinate distribution of the indices; an average calculation unit configured to calculate average values of the indices respectively corresponding to a plurality of segments in the polar coordinate distribution; a display unit configured to display the polar coordinate distribution and the short-axis image; an operation unit configured to designate a point of interest on a vein of the displayed short-axis image; and a segment setting unit configured to set a boundary of the segment at a position on the polar coordinate distribution which corresponds to a position of the designated point of interest.
