Abstract
The invention relates to a detector element for x-radiation, which can be used in particular in a flat dynamic x-ray detector (FDXD). In the detector element, a directly converting conversion layer () is arranged between an electrode layer () and a matrix of pixel electrodes (), there also being a photoconductive separating layer () between the pixel electrodes () and the conversion layer (). In the unilluminated state, the separating layer () acts as an electrical barrier for free charge carriers of the conversion layer (), which have been produced by x-radiation and migrate in the electric field between the electrodes (). After readout of the charge transfers in the pixel electrodes (), the separating layer () can be rendered conductive by illumination with reset light from a diode arrangement (), so that charge accumulations at its interface can flow away. The separating layer () can prevent perturbing dark currents, while charge accumulation can at the same time be avoided by the repeated reset phases.
