摘要： A three-dimensional ultrasonic diagnostic apparatus includes a two-dimensional array type of ultrasonic probe. A three-dimensional scan operation of scanning a three-dimensional region within a human body under examination with ultrasound and a two-dimensional scan operation of scanning a two-dimensional plane within the three-dimensional region with ultrasound are selectively performed by a beam former unit. Under the control of a controller, the three-dimensional scan operation is repeated intermittently and the two-dimensional scan operation is repeated during the interval between each three-dimensional scan. Three-dimensional ultrasonic image data concerning the three-dimensional region is produced on the basis of received echo signals obtained by the three-dimensional scan operation. Two-dimensional ultrasonic image data concerning the two-dimensional plane section is produced on the basis of received echo signals obtained by the two-dimensional scan operation.

摘要： In general, according to one embodiment, an ultrasonic diagnostic apparatus includes an image generating unit configured to generate medical images from a multislice which covers an area including the heart of an object. Each slice is almost perpendicular to the long axis of the heart. Each medical image is a short-axis image of the heart. A series of medical images captured at different times correspond to each slice. The embodiment generates a polar map associated with myocardial motion indices from a plurality of medical images. A polar map is segmented into segments. The embodiment calculates the average value of motion indices for each segment. The utility of an average value depends on the range covered by each segment. This embodiment matches the boundary of a segment with the position of a vein. This prevents a deterioration in the utility of average values due to the influences of veins.

摘要： When displaying a plurality of images in different conformations in relation to information of a tissue motion typified by a heart wall motion, support information which is used to rapidly and easily visually confirm a relative positional correspondence relationship between an MPR image, a polar mapping image, and a three-dimensional image is generated and displayed. A marker indicative of a desired local position is set and displayed as required. Further, a position corresponding to the set or changed marker may not be present on the MPR image. In such a case, the MPR image always including a position corresponding to the set or changed marker is generated and displayed by automatically adjusting a position of an MPR cross section.

摘要： Position coordinate information of each point three-dimensionally forming a tissue corresponding to a diagnosis target at each time phase is obtained, a quantitative value for evaluating the movement of the tissue corresponding to the diagnosis target is calculated by using the position information, and the result is output in a predetermined form. Accordingly, since the quantitative value for evaluating the movement is calculated by using the three-dimensional position coordinate information without converting wall movement information obtained by a three-dimensional tracking process into two-dimensional information, it is possible to provide medical information with a higher degree of precision.
