ABSTRACT:
A method for restoring navigation failure information in a fluoroscopy-based imaging system is disclosed. The method includes obtaining a plurality of receiver navigation information using a calibration target rigidly attached to a supporting member of the imaging system. The calibration target may include a plurality of receivers providing navigation information and the supporting member may be a C-arm. The method identifies a navigation failure and corresponding to the navigation failure a calibrated receiver navigation information is generated. The calibrated receiver navigation information is generated using a calibration information and a C-arm imaging position obtained during navigation failure. A receiver navigation information corresponding to the navigation failure is estimated using the calibrated receiver navigation information, and a transmitter navigation information. Also disclosed is a restoration unit for restoring navigation failure information in a fluoroscopy-based imaging system and a fluoroscopic imaging system using the restoration unit.
