WebThe Indirect conversion flat panel detector, on the other hand, converts X-rays into light via a layer of scintillator material which could either be cesium iodide or gadolinium oxysulfide. The amorphous silicon detector array lies behind the scintillator material. WebIndirect conversion flat panel detectors have a scintillator layer which converts x-ray photons to photons of visible light and utilise a photo diode matrix of amorphous silicon to subsequently convert the light photons into an electrical charge.

WebFeb 1, 2009 · Indirect conversion systems use a two stage technique for conversion. They have a scintillator, such as Cesium Iodide (CsI) that converts X-rays into visible light at a first stage. That light is then converted – at a second stage – into an electric charge by means of an amorphous silicon photodiode array. 8 WebFeb 27, 2016 · Indirect Conversion Indirect-conversion detectors are similar to direct detectors in that they use TFT technology.
