VERSATILE STEREOTACTIC DEVICE AND METHODS OF USE

摘要

A stereotactic device for use with an image, which permits an imaging scan to be taken with reference to a personal coordinate system (PCS) that is independent of a machine coordinate system (MCS). Methods using the device to obtain imaging scans (28) are described such that the imaging scans are superimposing even if taken at different time periods using the same or a different image. The device comprises a frame (10) that can be reproducibly positioned on a subject, and which is equipped with non-invasive affixing means (12, 14) and localizing means (16A, 16B, 18A, 18B, 20A, 20B) that provide the PCS. The device and method steps are particularly well suited for routine initial or follow-up examinations, pre-surgical planning and post-surgical evaluation.
