Patent ID: 7435965

Claim:
An X-ray detector, comprising: a plurality of layers arranged having a bottom layer and at least a second layer, a third layer and a fourth layer stacked on top of the bottom layer in succession in a direction parallel to a direction of the x-rays, each of the plurality of layers comprising: at least one photodiode that is produced from a semiconducting organic material and is applied on a film sub-layer, and a luminophore sub-layer applied on the photodiode, and a light-reflecting sub-layer provided on the luminophore sub-layer, the bottom layer comprising a photodiode matrix formed of a plurality of photodiodes that include the at least one photodiode of the bottom layer; the second layer comprising a photodiode matrix formed of a plurality of photodiodes that include the at least one photodiode of the second layer; said third layer comprising a photodiode matrix formed of a plurality of photodiodes that include the at least one photodiode of said third layer; said fourth layer comprising a photodiode matrix formed of a plurality of photodiodes that include the at least one photodiode of the fourth layer; the at least one photodiode of the bottom layer being arranged displaced relative to the at least one photodiode of the second layer; the at least one photodiode of the third layer being arranged displaced relative to the at least one photodiode of the fourth layer, with the at least one photodiode in each of said bottom layer and said third layer overlying one another, and the at least one photodiode in each of said second and fourth layers overlying one another to spectrally resolve an x-ray spectrum that is incident on said plurality of layers; and an amplifier associated with the at least one photodiode in said bottom layer in said bottom layer directly below the at least one photodiode in said second layer.
