Abstract
The present invention relates to a method and arrangement for detecting substantially the entire signal from a photon converting in a detector in an x-ray detecting arrangement (200, 300, 400), which results in charge-sharing, said arrangement comprising a number of spaced apart sensors (220, 320, 420), said detected photons indirectly creating an amount of free charges proportional to the photon energy. The method comprises the steps of arranging a blocking means (230, 330, 430) between said spaced apart sensors for stopping x-rays that will be incident close to edges of said sensors and will give rise to charge sharing between adjacent sensors. The blocking means comprises etched layers composed together to a blocking layer. The arrangement comprising said blocking means.

A method for detecting substantially an entire signal from a photon that is converting in a detector in an X-ray detecting arrangement, said arrangement comprising a photon converting device and a photon detecting device and a number of spaced-apart sensors, said detected photons indirectly creating an amount of free charges proportional to the photon energy,
- characterized by arranging a blocking means between said spaced-apart sensors for stopping X-rays that will be incident close to edges of said sensors and that would otherwise give rise to charge sharing between adjacent sensors, said blocking means being produced through etching layers combined together to form a blocking layer.
In an assembly for detecting and counting photons in x-ray beams, an arrangement when detecting substantially the entire signal from said photons converting in a detector in an x-ray detecting arrangement (200, 300, 400) comprising a number of spaced apart sensors (220, 320, 420), said detected photons indirectly creating an amount of free charges proportional to the photon energy
- characterised in
- that said arrangement comprises a blocking means (230, 330, 430) between said spaced apart sensors for blocking charge sharing between the sensors, said blocking means comprising etched layers (431) composed together to a blocking layer.
An assembly for detecting and counting photons in X-ray beams, the assembly comprising a number of spaced-apart sensors, said detected photons indirectly creating an amount of free charges proportional to the photon energy, the assembly further comprising a blocking means, produced through etching layers, between said spaced-apart sensors for blocking charge sharing between the sensors.
