ABSTRACT:
Embodiments of an X-ray diagnostic imaging system comprise a plurality of coded 2D and/or 3D markers associated with surfaces of system components. The position and coding of at least some of the coded markers can be determined by a position detection system. In some embodiments, a coded marker is assigned a reference point having a known position on the surface of the system component. The positions of the system components in space can be calculated based at least in part on a reference point network determined from the position of the individual reference points measured with the position detection system. In some embodiments, the coded markers represent information with a data matrix code (DMC).
