VERSATILE STEREOTACTIC DEVICE AND METHODS OF USE
First Claim
1. A method of using a radiographic device, comprising the steps of:
- a. establishing a personal coordinate system referenced to the body of a living organism;
b. establishing a linkage between said personal coordinate system and a machine coordinate system of said radiographic device; and
c. translating data captured in said machine coordinate system to data referenced in said personal coordinate system.

Abstract
A stereotactic device for use with an imager such as a magnetic resonance imager 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 scans are described such that the imaging scans are superimposable even if taken at different time periods using the same or a different imager. The device comprises a frame that can be reproducibly positioned on a subject and which is equipped with non-invasive affixing means 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.
