Abstract:
1. An ultrasonic diagnosis apparatus comprising: an ultrasonic probe; an ultrasonic transmission/reception unit configured to transmit an ultrasonic wave to an object and receive a reflected wave corresponding to the transmitted ultrasonic wave from the object via the ultrasonic probe and to generate a received signal based on the received reflected wave; a volume data generating unit configured to generate volume data based on the received signal; a projected image generating unit configured to generate a projected image based on the volume data and a predetermined line-of-sight direction; a two-dimensional region-of-interest setting unit configured to set a two-dimensional region of interest on the projected image; a specifying unit configured to specify a plurality of voxels based on pixels in the two-dimensional region of interest and the predetermined line-of-sight direction; a calculation unit configured to calculate a contribution degree of each of the specified voxels which contributes to a value of the pixels in the two-dimensional region of interest based on a voxel value and opacity of each of the plurality of voxels; and a three-dimensional region-of-interest determination unit configured to determine a position of a three-dimensional region of interest in the volume data based on the contribution degree.
