Systems and methods for integrating a navigation field replaceable unit into a fluoroscopy system

A method for imaging system calibration, said method comprising:

• obtaining navigation information using a calibration target positioned with respect to a detector between an energy source and an image acquisition device in an imaging system, said calibration target including a plurality of receivers providing navigation information;
• determining a receiver coordinate system for the imaging system based on said navigation information;
• and
• obtaining image calibration data using an array of radio opaque fiducials arranged around a periphery of the detector between the image acquisition device and the energy source.

A calibration target system for use in an imaging environment, said system comprising:

• a frame for positioning a plurality of components with respect to a detector mounted on a support member in an imaging environment;
• an array of radio opaque fiducials mounted on said frame, said array of radio opaque fiducials arranged to provide image calibration information;
• a plurality of receivers positioned on said frame around a periphery of the detector to provide navigation information;
• and
• a shield arranged with respect to said frame to cover sides of the detector.
