SYSTEM AND METHOD FOR AUTOMATIC CALIBRATION OF TRACKED ULTRASOUND

摘要

A system and method of tracking ultrasound transducers or probes (12) with spatial localizers (16) achieves automatic calibration with a minimum addition of hardware to that required by earlier systems. An image-based tracking algorithm localizes control points in an image space (I). An unlimited number of points can then be used for ultrasound calibration, allowing for high calibration accuracy. The proposed calibration system (10) is simple and low cost. The calibration is fast and can be carried out automatically. FIG. 1
