Abstract:
A stereotactic localizer system for localizing positions in a patient's anatomy based on an image scan of said patient's anatomy comprising:a. a skin band adapted to be fixed to the patient's skin of said patient's anatomy;b. reference markers connected to said skin band and detectable in image scan data produced by said image scan and having image positions in an image scan coordinate system and/or said image scan data, and having physical positions with respect to stereotactic coordinate system associated with an external apparatus near said patient's anatomy, such that said image scan coordinate system can be mapped into said stereotactic coordinate system by a transformation from said image positions to said physical positions; and,c. further including dynamic reference structures attached to said skin band, said dynamic reference structures having a pattern which can be detected by a detection apparatus that is in a position with respect to said stereotactic coordinate system, such that changes in position of said patient's anatomy with respect to said stereotactic coordinate system can be detected by said detection apparatus and accordingly corrections in said mapping between said image scan coordinate system and said stereotactic coordinate system can be made.
