At present, there are more and more x ray detectors used in digital X-ray machines. Let me introduce some knowledge of flat panel detectors used in digital X-ray machines.
Flat panel detectors appeared in the 1990s and were used in the medical field before moving to the field of non-destructive testing. The device is composed of a disk-shaped, its width and the length of each pixel, the size of the human hair as a unit of X-ray exposure, a very good thin-film semiconductor detector based on the composition Guiwei array, And each pixel collects and stores charge, and each pixel can be digitized, so a two-dimensional image is displayed on the display
Unstructured products use the X-ray scintillator photodiode loading mode of the silicon plate, the scintillator layer, which is usually CSI-thallium-doped crystals used to receive X-ray photons that are converted into visible light, sent along the iodide pin in the photodiode The generated photodiode, due to the light irradiation current, current is accumulated in the charge of the photodiode is formed. The amount of charge proportional to the incident radiation dose should be within the range of the photodiode, the completed X-ray dose.
It is suitable for digital medical X-ray machines, chest radiograph holders, etc.
