ABSTRACT:
A method and apparatus is described for making a custom fixation device. The apparatus comprises a means for scanning a treatment site and for producing image data representative of the treatment site. A means for generating a set of vectors is included for defining a set of points, the set of vectors representative of the treatment site, the points associated with a surface, part of the surface representative of part of the treatment site, part of the surface hidden from view. Further, means for associating each point with a pole of a control polygon of a non-uniform rational B-spline, means responsive to the non-uniform rational B-spline for constructing a model of the treatment site, and means responsive to the model for constructing the fixation device are described.
