X-ray detector having sensors and evaluation units |
摘要 |
An X-ray detector includes an array of X-ray sensitive sensors, each sensor including a conversion element which converts incident X-rays into electric charge pulses. The X-ray detector also includes an evaluation unit which is electrically connected to the conversion element in order to receive and evaluate the electric charge pulses. In order to form an X-ray detector which exhibits a high degree of linearity over a large dynamic range in conjunction with a higher maximum count rate and in order to avoid falsification of the calculated image by multiple counting of X-ray quanta, the evaluation unit includes a current/frequency converter as well as an electronic counter which is electrically connected thereto. The electric charge pulses from the conversion element are applied to the input of the current/frequency converter whose output pulses are applied to the electronic counter.
