BIOLOGICAL TISSUE MOTION TRACE METHOD AND IMAGE DIAGNOSIS DEVICE USING THE TRACE METHOD

摘要

PPROBLEM TO BE SOLVED: To provide a biological tissue motion trace method which uses a tomographic image to quantitatively measure tissue motion. PSOLUTION: One frame image of a moving image formed by producing tomographic images of an object to be examined is displayed (S2), a mark is superposed on a designated portion of a biological tissue the movement of which is tracked in the displayed one frame image (S3), a cutout image of a size including the designated portion is set in the one frame image (S4), frame images are searched in other frame images of the moving image and a frame image of the identical size which is most coincided with the cutout image is extracted (S5, 6), and coordinates of the designated portion after movement is calculated based on the difference between the most coincided frame image coordinates and the cutout image coordinates (S7), and thereby the movement of the tissue is quantitatively measured.
