Abstract:
A method for mapping coordinates between images and tracking systems includes providing a calibration tool having a fixed geometric shape. The calibration tool includes first sensors associated with an imaging mode and second sensors associated with a tracking mode. The first and second sensors are distributed and mounted at known locations on the fixed geometric shape. The first sensors are located in a field of view of an imaging system to determine a position of the calibration tool in image space. The second sensors are tracked to determine a same position of the calibration tool in tracking space. The image space and the tracking space are mapped in a common coordinate system based on artifacts of the calibration tool.
