The difference between amorphous silicon scintillator coating materials cesium iodide and gadolinium oxysulfide

There are two common amorphous silicon scintillator coating materials: cesium iodide and gadolinium oxysulfide. Cesium iodide has a stronger ability to convert X-rays into visible light than gadolinium oxysulfide, but the cost is relatively high; processing cesium iodide into a columnar structure can further improve the ability to capture X-rays and reduce scattered light. Detectors using gadolinium oxysulfide coating have fast imaging speed, stable performance and low cost, but the conversion efficiency is not as good as that of cesium iodide coating. The materials and processes of the scintillator coating affect the ability of X-rays to be converted into visible light and therefore have an impact on DQE.

Basic knowledge of gadolinium oxysulfide (GOS) amorphous silicon detectors

Differences between different X-ray detectors. Gadolinium oxysulfide (GOS) amorphous silicon detector consists of a scintillator or phosphor layer coated with an amorphous silicon layer (used as a photodiode). The scintillator is required to convert X-rays into visible light, which is then converted by the photosensitive element. The visible light is converted into electrical signals, and then the imaging is switched through the TFT array. This is also indirect digital photography.
