VERSATILE STEREOTACTIC DEVICE AND METHODS OF USE

摘要

A stereotactic device for use with an imagery such as a magnetic resonance imagery is disclosed, which permits an imaging scan to be taken with reference to a personal coordinate system (or PCS) that is independent of a machine coordinate system (or MCS). Methods using the device to obtain imaging imposing scans are described such that the imaging scans are super-imposed even if taken at different time periods using the same or a different imagery. The device comprises a frame (10) that can be reproducible positioned on a subject which is equipped with a non-invasive affixing means (12, 14), and localizing means that provide the PCS. The device and methods of the invention are particularly well suited for routine initial or follow-up examinations, pre-surgical planning and post-surgical evaluation. Markers on a stereotactic device can be tracked during an MRI scan to compensate for patient motion during the scan.
