Abstract: Certain embodiments of the present invention provide systems and methods for electromagnetic calibration of an instrument. Certain embodiments provide an electromagnetic instrument calibration system including electromagnetic receiver electronics for receiving electromagnetic field information from an electromagnetic transmitter. The system also includes a calibration mount configured to position the electromagnetic receiver electronics stationary with respect to the calibration mount for calibrating an instrument having an electromagnetic transmitter using the calibration mount and the electromagnetic receiver electronics.

Abstract: A calibration apparatus for a medical device is disclosed herein. The calibration apparatus includes a locating member configured to locate a first predetermined portion of the medical device. The calibration apparatus also includes a calibration member positioned relative to the locating member such that, when the calibration apparatus is attached to the medical device, the calibration member aligns with a second predetermined portion of the medical device. A corresponding method for determining the location of the second predetermined portion of the medical device is also provided.

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.
