A MEDICAL IMAGE-UNDERSTANDING SYSTEM

This paper presents a general methodology for computer interpretation and integration of medical images. Ai I explicit anatomical model, as well as other domain knowledge, is used to facilitate feature extracti on and the fusion of images from different modalities. A frame represe ntation is used to implement the description of important anatomical f eatures and other domain knowledge. Frames are also used to implement the control mechanisms that establish communication between the image data and the symbolic knowledge. A prototype system for reconstructing the human cerebral vasculature is presented. (C) 1997 Elsevier Scienc e Ltd. All rights reserved.
