Abstract
A system for obtaining coordinate data of a source and detector instrument are described. The system includes a marker assembly having a plurality of markers with a particular geometry, and an energy source for targeting the plurality of markers with energy packets. The system further includes a detector for detecting energy packets after the plurality of markers have interacted therewith, and an image device for forming image data of the plurality of markers from the energy packets detected by the detector. A calibration module for utilizes the particular geometry of the plurality of markers and the image data to non-iteratively determine coordinate data.
