X-ray calibration dummy, a method for non-marker-based registration for use in navigation-guided operations employing said x-ray calibration dummy, and a medical system having such an x-ray calibration dummy

摘要

An X-ray calibration dummy (RP) having markings (4) that may be acquired by a position-acquisition system (30). The invention also concerns a method for nonmarker-based registration for use in navigation-guided operations employing the X-ray calibration dummy (RP). A medical system for carrying out the method has a C-shaped X-ray machine (10), a position-acquisition system, 30, and the X-ray calibration dummy (RP).
