ARRANGEMENT OF NOTABLE ELEMENTS OF ORGANS AND THREE- DIMENSIONAL EXPRESSION METHOD THEREOF

PROBLEM TO BE SOLVED: To reduce risk of error in selecting a region to be punctured by selecting elements to be noticed existing in a digital image, deciding three- dimensional coordinates of each notable element, expressing the notable elements three-dimensionally, and selecting one or plural notable elements manually. SOLUTION: At first, in stage 1, some of the three-dimensional localized images of X-ray photography are produced. Then, in stage 2, regarding autodetection of notable elements, they are matched in the process of stage 3a for obtaining three-dimensional coordinates. Stage 3d is sometimes carried out with stage 3a simultaneously or instead of it to constitute a three- dimensional image of a specially noticed element. Then, stage 4 enables expression of three-dimensional space of notable elements on the screen, and one or plural ones among them is (are) selected in the process of stage 5, and these coordinates are sent to a three-dimensional positioning apparatus in the process of stage 6.
