Claim One:
1. A method for identifying an orientation of an apparatus used in the treatment of a patient's anatomy as determined from computer tomographic (CT) image data, said method comprising the steps of: (a) attaching CT detectable markers onto a patient's anatomy to form coordinate markers in the CT imaging data which identify the position of the markers relative to the patient's anatomy; (b) generating CT imaging data of the patient's anatomy, said CT imaging data containing data identifying the position of the CT detectable markers relative to the patient's anatomy; (c) taking images of the patient from at least one direction with an imaging means, said imaging means being positioned relative to said apparatus, for detecting said detectable markers whereby the orientation of said patient's anatomy as visualized in said CT image data relative to said apparatus is determined relative to said imaging means.
