Patent ID: 8581254

Claim:
A radiation detector module, comprising: a thin film transistor (TFT) array; a photodetector disposed beneath the TFT array, the photodetector comprising: a cathode disposed beneath the TFT array; an active organic element disposed beneath the cathode; and an anode disposed beneath the active organic element, wherein the cathode is reflective on a side facing the active organic element, and wherein the reflective side of the cathode is configured to reflect optical photons generated by the scintillator back to the active organic element; an adhesive layer, wherein the TFT array is physically bonded to the photodetector by the adhesive layer; and a scintillator substrate disposed beneath the photodetector, wherein the scintillator substrate absorbs radiation passing through the TFT array and the photodetector and emits optical photons in response to the absorbed radiation, and wherein the photodetector absorbs optical photons emitted by the scintillator and generates charge in response to the absorbed optical photons.
