Patent ID: 7145985

Claim:
A sensor arrangement for a sensor in digital scanning imaging utilizing electromagnetic radiation, the arrangement comprising a radiation absorbing element which includes or to which is integrated material converting radiation quanta into electron-hole pairs, pixel electrodes (P 1 , P 2 , P 3 ) on a surface opposite to a radiation-receiving surface of said element for dividing the element into pixels, counters (C) which are connected to said pixel electrodes (P 1 , P 2 , P 3 ) for counting pulses received therefrom, counter-specific switching means (Sm) that are arranged between the counters (C) and the pixel electrodes (P 1 , P 2 , P 3 ) such that in a scanning direction of the sensor, successive structures are obtained, where one counter (C) and one switching means (Sm) are arranged for every N successive pixel electrodes (P 1 , P 2 , P 3 ), N being an integer whose value is at least two, to which switching means (Sm) are connected sets of pixel electrodes (P 1 , P 2 , P 3 ) consisting of 2N−1 successive pixel electrodes (P) such that of each set the midmost pixel electrode (P 2 ) is connected to only one switching means (Sm), the pixel electrodes (P 1 ) preceding said midmost pixel electrode (P 2 ) are arranged connectable to both said one switching means and one preceding switching means (Sm), and pixel electrodes (P 3 ) subsequent to said midmost pixel electrode (P 2 ) are arranged connectable to both said one switching means and one subsequent switching means (Sm).
