ABSTRACT:
A computed tomography system which includes both a high-energy imaging apparatus (such as an X-ray computed tomography device) and also one or more phantoms whose solid characteristics generally correspond to the density and shape (preferably including external and internal contours) of the existing object to be imaged. The phantom is used for differential error-correction techniques, which permit very accurate imagining of the contours of bones in vivo. The accurate images thus derived permit fabrication of orthopedic prostheses which have an extremely accurate fit to existing bone structure.
