<p>A method and an apparatus for specifying slice planes in an X-ray CT, capable of specifying a slice plane corresponding to the desired tomographic image easily and accurately. In the apparatus, scans of the body to be examined are carried out and the projection data are stored in the large capacity memory (11) first. Then, a scanogram of the body to be examined is displayed, on which a cursor (21,31,41) is controlled in order to specify the desired slice planes corresponding to the desired tomographic images to be reconstructed. Then, the desired tomographic images are reconstructed for the desired slice planes indicated by the cursor by using an appropriate part of the projection data stored in the memory (11) which corresponds to the desired slice planes indicated by the cursor (21,31,41). Either one of the helical scan and the multi-scan can be used for collecting the data to obtain the scanogram and the tomographic images (23,33). <IMAGE></p> |
