Abstract
An ultrasound diagnostic apparatus which forms a three-dimensional bloodstream image by reference to volume data obtained from a three-dimensional space within a living organism. Binarization processing and three-dimensional labeling processing are applied to velocity volume data, to thereby generate three-dimensional mask data. At this time, because a bloodstream object has a larger volume size than a noise object, this difference in volume size is utilized to discriminate between a bloodstream portion and a noise portion. Bloodstream volume data are then generated from the velocity volume data and by reference to the three-dimensional mask data. Then, a three-dimensional bloodstream image is formed by reference to the bloodstream volume data.
Claims17
An ultrasound diagnostic apparatus, comprising:
- a unit which transmits and receives ultrasonic waves with respect to a three-dimensional space within a living organism to obtain original volume data;
- a computation unit which extracts motion information from the original volume data to generate motion volume data;
- an identification unit which specifies a plurality of objects included in the motion volume data and identifies a type of each of the objects which are specified to thereby generate identification data;
- an extraction unit which extracts bloodstream volume data from the motion volume data by reference to the identification data;
- and
- an image-forming unit which forms a three-dimensional bloodstream image by reference to the bloodstream volume data.
An image-processing program to be executed in a computer, for forming a three-dimensional bloodstream image by reference to motion volume data, the image-processing program comprising:
- a module which specifies a plurality of objects included in the motion volume data and determines whether or not each of the objects which are specified is a bloodstream to thereby generate identification data;
- a module which extracts bloodstream volume data from the motion volume data by reference to the identification data;
- and
- a module which forms a three-dimensional bloodstream image by reference to the bloodstream volume data.
