Ultrasound diagnosis apparatus, computer program product, and control method

An ultrasound diagnosis apparatus that generates fly-through image data on a hollow organ on the basis of various sub-volume data that are acquired by transmitting/receiving ultrasound to/from a three-dimensional region in a subject, the ultrasound diagnosis apparatus comprising:

• a viewpoint-boundary distance measuring unit that measures, as a viewpoint-boundary distance, a distance between a viewpoint that is set in the hollow organ in the sub-volume data and that moves in a direction in which the hollow-organ runs and a boundary between the adjacent sub-volume data;
• a viewpoint movement controller that controls, on the basis of the result of measuring the viewpoint-boundary distance, a speed at which the viewpoint moves;
• a fly-through image data generator that generates the fly-through image data by processing the sub-volume data on the basis of the viewpoint;
• and
• a display unit that displays the fly-through image data.

A computer program product including a computer-readable recording medium including instructions for generating fly-through image data on the basis of various sub-volume data that are acquired by transmitting/receiving ultrasound to/from a three-dimensional region in a subject, the instructions causing a computer to perform:

• correcting misregistration between the sub-volume data on the basis of at least any one of information on a lumen wall of a hollow organ and information on a core line that indicates the center axis of the hollow organ in the sub-volume data;
• generating the fly-through image data on the basis of sub-volume data where the misregistration has been corrected;
• and
• displaying the fly-through image data.
