WO15044421A2 [EN] The invention relates to an x-ray detector for detecting x-radiation comprising a first sensor layer having at least one sensor cell, a second sensor layer having at least one sensor cell, and a third sensor layer having at least one sensor cell. The at least three sensor layers are arranged one behind the other in an irradiation direction of the x-radiation. The sensor cells of the first, second, and third sensor layers are designed to each output a sensor signal lx in dependence on the x-radiation acting thereon. On the basis of the sensor signals lx of the sensor cells of the at least three sensor layers, a progression of an energy deposition over a penetration depth through the at least three sensor layers can be determined.
