Abstract

In a multi-modality method for representing functional and morphological exposures of an extremity of patients exhibiting arthritis/arthrosis, and corresponding computer software, images obtained with different imaging modalities are supplied to a computer and displayed at the computer with a default line model of the extremity superimposed on each of the images. A user interacts with the computer to modify the line model as necessary, so that each of the images has a modified line model associated therewith. The images obtained from the different imaging modalities are then superimposed and registered with each other by conforming the respective modified line models with each other. One of the images can be composed of a number of sub-images, obtained at respective joints in the extremity. These individual images of the joint can be fused with the image of the complete extremity, so that in a display of such a fused image, the individual joint images can be selected and displayed.
