Beschreibung
Zusammenfassung:	The invention relates to an X-ray imaging device including a rotary collimator having a region (22) which is opaque to X-rays, a first slot (24) and a second slot (26), which are transparent to X-rays and extend in two different directions, passing through said opaque region, the collimator making it possible to determine the position of an element provided with X-ray sensors in an imaging system. Dispositif pour l'imagerie par rayons X comprenant un collimateur tournant ayant une région opaque (22) aux rayons X, cette région opaque étant traversée par une première fente (24)et une deuxième fente (26) transparentes aux rayons X et s'étendant dans deux directions différentes, le collimateur permettant de déterminer la position d'un élément muni de capteurs de rayons X dans un système d'imagerie.
