Definitions and differences between scintillators and phosphors of amorphous silicon X-ray flat-panel detector

Definitions and differences between scintillators and phosphors of amorphous silicon X-ray flat-panel detectors: usually we refer to the luminescent materials that can produce visible light under X-ray irradiation as scintillators or phosphors. The difference between the two is , Fluorescence refers to the process of continuous light emission after the X-ray machine stops, and flicker refers to the lightning pulse of a single high-energy particle on the scintillator, that is, the scintillator instantly glows in a flashing shape after X-ray irradiation. After being irradiated by X-rays, it glows continuously.

After the X-ray enters the amorphous silicon X-ray flat-panel detector, the scintillator or fluorescent material on the surface converts the X-ray photons into visible light (the phenomenon of light scattering will occur and affect the image spatial resolution), and then the amorphous silicon will convert the visible light Converted into stored charge, the stored charge enters the readout circuit to convert the charge signal into a digital signal, complete the digital acquisition process, and then input the digital signal into the computer imaging system of the computer for imaging.

The surface of the amorphous silicon X-ray flat-panel detector is a layer of scintillator (cesium iodide) or phosphor material (sulfur oxide rolling), below is a layer of amorphous silicon with photodiode function, and the bottom layer is a layer of charge reading Out of the circuit.See here that everyone has a clearer understanding of amorphous silicon X-ray flat-panel detectors.
