based processing of radiological images". Different imaging modalities, for example X-Ray CT and NMR, generate markedly different images from the same anatomy. Investigating the nature of the images produced has allowed us to develop a low level domain independent segmentation algorithm. A scheme to perform further merging has been developed, based on rules and a current world model derived from the anatomy, the modality and non-visual knowledge^. This final stage produces a segmented world representation of the image which is directly comparable to the original current world model. The X-Ray CT and NMR imaging techniques provide a non-invasive window for the examination of in
