Abstract
The present invention relates to a photon counting X-ray detector and detection method that effectively suppress polarization even under high flux conditions. The proposed detector comprises a photon counting semiconductor element () for generating electron-hole pairs in response to incident X-ray photons, a cathode electrode () arranged on a first side () of said semiconductor element () facing incited X-ray radiation, said cathode electrode comprising two interdigitated cathode elements (), a pixelated anode electrode () arranged on a second side () of said semiconductor element () opposite said first side (), a power source () for applying a bias voltage between said cathode electrode and said anode electrode and for temporarily applying an injection voltage between said cathode elements (), and a readout unit () for reading out electrical signals from said pixelated anode electrode ().
