Claim Text:
1. A pixel detector, comprising a semiconductor sensor layer, in which charges can be liberated upon interaction with particles to be detected, said semiconductor layer defining an X-Y-plane and having a thickness d extending in a Z-direction, and a read-out electronics layer electrically connected to said semiconductor layer, said read-out electronics layer comprising an array of read-out circuits for detecting signals indicative of charges generated in a corresponding volume of said semiconductor sensor layer, wherein neighbouring read-out circuits are connected by a relative timing circuit configured to determine time difference information between signals detected at said neighbouring read-out circuits, said time difference information being indicative of a difference in Z-components of the locations of charge generations in the corresponding neighbouring sensor volumes caused by a particle trajectory that is inclined with respect to the X-Y-plane.
