1. A medical tracking system, comprising:
a localization system operative to define a coordinate system and to detect position signals from a marker device which indicate the position of the marker device; a computer operative to assign positions to medical instruments in the coordinate system, wherein the computer is operatively coupled to the localization system; at least one localizable gamma camera operative to detect gamma radiation emitted from a tracer material, wherein the gamma camera is operatively coupled to the computer; wherein the marker device is attached to the gamma camera in a fixed positional relationship relative to the gamma camera, wherein the position of the gamma camera in the coordinate system is assignable by the computer based on the position signals detected by the localization system; at least one medical instrument including a marker attached thereto, wherein the marker attached to the medical instrument contains a tracer material which emits gamma energy and wherein the marker attached to the medical instrument is positionally fixed relative to the at least one medical instrument and detectable by the gamma camera, wherein the computer is operative to assign, based on the gamma radiation emitted from the marker which emits gamma energy and detected by the gamma camera, and based on the position of the gamma camera determined by the position signals detected by the localization system, a position to the marker which emits gamma energy. |
