An expert system for radiological images

We present an expert system developed to confirm or to assess the presence of a pathology on the basis of morphological data, coming from radiological images. This system is based on object oriented programming. The basis of this system is a lingustic description of the radiological image referred as "feature image". We can recognise three different levels of use. The first from a real image to some possible pathologies, the second from some pathologies to a possible expected image, the third, a consultation level on the anatomical region considered. We have tested the system on images of the thorax.
