Mathematical methods using CT and MR images for stereotactic neurosurgery.

A new application area in the practical usage of magnetic resonance imaging (MRI) has been identified as a methodology of stereotactic operation. In particular, our approach provides a solution for the straightforward definition of target and trepanation points for the purposes of stereotactic neurosurgical operation, and an exact testing of its result. The definition of the proper transformation between different examination data sets is a crucial mathematical problem. This is well done by morphing and the thin plate spline method.
