Abstract
This invention relates to the quantitative determination of a target or volume in the living body relative to external apparatus based on CT (computer tomography) or other image data. The invention describes a means of taking CT image data of the anatomy and of natural or implanted index positions on the patient's body, and relating the CT data to a coordinate system related to external apparatus which may be in fixed position relative to the patient. One implementation uses a transformation between the CT image data coordinate system and the second coordinate system. This makes it possible to do frame-based or frameless stereotactic target identification and approaches without the need for attaching a frame to the patient at the time of CT scanning.
