Abstract:
1. An imager for imaging a subject illuminated by incident radiation, said imager comprising: a substrate comprising a polymer; a photosensor array disposed on said substrate, wherein said photosensor array comprises a plurality of photosensors and an addressable thin film transistor (TFT) array comprising a plurality of TFTs, wherein each of said TFTs is electrically coupled to a respective one of said photosensors so as to selectively address respective photosensors in said photosensor array, and wherein each of said TFTs comprises a gate electrode, a semiconductive region comprising an organic semiconductor and disposed over said gate electrode, and a source electrode and a drain electrode in contact with said semiconductive region; and a scintillator disposed so as to receive and absorb the incident radiation, configured to convert the incident radiation to optical photons, and optically coupled to said photosensor array, wherein said photosensor array is configured to receive the optical photons and to generate an electrical signal corresponding to the optical photons.
