A comprehensive expert assistant system is being developed with initial application to chest X-rays. This system is characterised by the use of explicit anatomical models for reasoning about the anatomy, and for visualising the anatomical structures identified in the image segmentation. The overall strategy is to compare a modality-independent model with the image(s) by way of an intermediate feature space. The system is implemented to identify major structures on chest X-rays, ·mainly using long edges. An explicit threedimensional anatomical model forms a major system component, and the object-oriented structure of this model permits adaptation and anatomical reasoning. The system is implemented in a frame structure using LISP, and features automatic and interactive segmentation of major landmarks in chest X-
