ABSTRACT:
Method and apparatus for producing CT images in which localized regions ("rub-out" regions) of the original object are not reproduced in order to eliminate artifacts generated by objects within those regions. An operator defines a rub-out region encompassing the object to be removed. The projection set is then modified by creating an average function within the rub-out region which is strongly influenced by the discontinuity created by the object. That information is then utilized to modify the projection set, in effect eliminating the object from the set. The projection set is then used to create a reconstructed image in the normal way.
