Abstract
A solid-state radiation detector includes an active pixel matrix, which is arranged at one side with a scintillator layer, which emits light that can be converted into electrical charge by the pixel matrix depending on incident radiation, in particular X-ray radiation, and which is arranged on a carrier at the other side. At least one layer that at least partly absorbs the light that originates from the scintillator layer and has penetrated into the carrier is provided at the carrier.
Claims15
A solid-state radiation detector comprising:
- an active pixel matrix, arranged at an upper side with a scintillator layer, to emit light convertible into electrical charge by the pixel matrix depending on incident radiation and arranged on a carrier at a lower side, wherein at least one layer that at least partly absorbs the light that originates from the scintillator layer and has penetrated into the carrier is provided at the carrier and is not directly adjacent to the active pixel matrix.
A solid-state radiation detector comprising:
- an active pixel matrix, arranged at an upper side with a scintillator layer, to emit light convertible into electrical charge by the active pixel matrix depending on incident radiation and arranged at a lower side on a carrier which is transparent to the light, wherein at least one layer that at least partly absorbs the light that originates from the scintillator layer and has passed through the carrier is arranged at a side of the carrier opposite and not directly adjacent to the active pixel matrix.
