ACCURATE AND RAPID MAPPING OF POINTS FROM ULTRASOUND IMAGES TO TRACKING SYSTEMS

摘要

A method for mapping coordinates between images and tracking systems includes providing (702) 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 (708) 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 (716) to determine a same position of the calibration tool in tracking space. The image space and the tracking space are mapped (722) in a common coordinate system based on artifacts of the calibration tool.
