摘要： An ultrasonic diagnostic apparatus either for displaying three-dimensional ultrasonic images allowing an operator to become aware of the distance of a target object from an ultrasonic probe, or for displaying practical three-dimensional ultrasonic images while being simply structured and taking a short time to perform necessary operations. The apparatus comprises: an ultrasonic beam data memory for storing B-mode ultrasonic beam data or CFM ultrasonic beam data; an address control unit for sequentially writing and reading the ultrasonic beam data to and from the ultrasonic beam data memory in the direction of depth; a three-dimensional operation unit for generating three-dimensional ultrasonic beam data using the ultrasonic beam data read from the ultrasonic beam data memory by the address control unit; a three-dimensional ultrasonic beam data memory for storing the three-dimensional ultrasonic beam data thus generated; a DSC (digital scan converter) for converting the three-dimensional beam data to a display-ready format; and a CRT.

摘要： In executing projection processing for the purpose of enhancing the efficiency of diagnosis, if a threshold is reached again after a specific value of a pixel reaches the threshold in the x direction in which tomographic planes are arrayed, the execution of the projection processing is ended, and a projected image is generated. Then, in generating that projected image by executing projection processing, tomograms are so synthesized with the projected image that the positions of the pixels projected in the x direction and the pixels of the tomograms generated in the x direction match each other in the scanned three-dimensional area of the subject, and the synthesized images are thereby generated.

A tracing unit traces movement of tissue in the target object corresponding to the first and second ROIs from the designated time to sequentially following thereafter by a gradient method using a spatial brightness gradient. A second memory unit stores information of the movement of the tissue for a predetermined duration.
