| 摘要 |
The invention relates to a flat panel X-ray detector comprising an array of sensor elements ( 3, 4 ) for converting X-ray radiation into electrical signals, said sensor elements containing at least one semiconductor diode having at least one sidewall where leakage current can occur, if said detector is connected to a voltage supply. It is an object of the invention to reduce the leakage current. This object is achieved by providing at least one influencing electrode ( 2, 14 ) adapted for influencing electric fields at said sidewall ( 10 ) for reducing the leakage current.
