Abstract: An ultrasound diagnostic system of the invention includes: an ultrasound probe that transmits and receives an ultrasound wave to and from an object; 3D position detection means configured to detect the position and inclination of a position sensor with respect to the object, the position sensor being mounted on the ultrasound probe; storage means configured to acquire and store 3D image data acquired by the ultrasound probe scanning on the body surface of the object and the position and inclination of the position sensor detected by the 3D position detection means; standard image data setting means configured to divide the 3D image data stored in the storage means into a plurality of slice image data and sets image position information and inclination information of a predetermined standard image data structure to the respective slice image data based on the position and inclination information of the position sensor detected by the 3D position detection means; and standard image data generation means configu

Abstract: An ultrasonic diagnostic apparatus includes a storage unit configured to store information about the contour of an object to be examined and information about the position of a specified region of the ultrasonic image of the object both corresponded to a body contour model coordinate system and a coordinate calculating unit configured to correspond the object coordinate system to the body contour model coordinate system according to the information about the position of the specified region of the object, associating with each other the object coordinate system and the body contour model coordinate system used when comparing an ultrasonic tomographic image based on ultrasonic tomographic data stored in an image storage unit with a real-time ultrasonic tomographic image scanned by an ultrasonic probe, and thereby calculating the coordinates of the scanned plane of the real-time ultrasonic tomographic image in association with the object coordinate system.

Abstract: In an image display apparatus capable of storing therein a small amount of images and also capable of displaying two sorts, or more of images within a short time period, an axial image 1, a sagittal image 2, and a coronal image 3, which are loaded from a magnetic disk, are displayed on a CRT monitor 117. Image position indication FIGS. 4, 5, 6 are indicated above the respective tomographic images, and positions of the respective tomographic images are indicated on the respective image position indication FIGS. 4, 5, 6 by employing heavy lines 4a, 5a, 6a, and triangular symbols 4b, 5b, 6b. The positions of the tomographic images can be adjusted by dragging the respective triangular symbols 4b, 5b, 6b by using a mouse 118. Image position input FIGS. 7, 8, 9 are indicated under the respective tomographic images, and the positions of the respective displayed tomographic images are indicated on the image position input FIGS. 7, 8, 9 by way of drag bars 7a, 8a, 9a.
