Abstract
A method is described for representing a treatment site (10) of a patient as data suitable for use with a computer-aided design device (46). The method includes scanning the treatment site(10) with a scanning apparatus (40), such as a CT scanner, to produce image data; determining the image data that represents the surface of the item; generating vectors from the determined data; and associating the vectors with poles of a non-uniform rational B-spline so that a polynomial equation may be generated, which is a data form suitable for use with CAD devices.
