Document Type and Number:
Japanese Patent JP2003527610
Kind Code:
A
Abstract:
A sensor arrangement and method for digital X-ray imaging. The sensor arrangement in digital X-ray imaging includes at least one sensor element which absorbs X-radiation and contains a medium, which has a relatively thin semi-conductor material structure, that converts X-ray quanta into electron-hole pairs. The surface of the element opposite to the surface receiving the X-radiation is provided with electrodes for dividing the sensor element into at least two pixel columns. Each pixel electrode is provided with detection electronics and a counter for counting the voltage or current pulses generated by the electron-hole pairs. The counters for adjacent pixel columns are connected to each other so that the counters for the pixels can be loaded from the counter for the corresponding pixel on the same row in the preceding pixel column. The counter may be provided with a circuit for preventing counting after the counter has reached its maximum value, ensuring that overexposure will not produce any other error in the image.
