FIELD: physics.
SUBSTANCE: system and method with tracked ultrasound transducers or probes (12) with spatial localisers (16) achieves automatic calibration with a minimum addition of hardware to that required by earlier systems. An image-based tracking algorithm localises control points in an image space (I). An unlimited number of points can then be used for ultrasound calibration, allowing for high calibration accuracy.
EFFECT: proposed calibration system is simple and cheap, and the calibration is fast and can be carried out automatically.
