What are the advantages and disadvantages of using gadolinium oxysulfide and cesium iodide in X-ray flat panel imaging technology?
X-ray flat panel detectors have different imaging principles for the two materials. Cesium iodide is a semiconductor material that can generate electron-hole pairs under the action of x-rays. Then these carriers will be collected by TFT capacitors under applied bias, and then different The amount of electricity in the pixel capacitor corresponds to the dose of transmitted radiation; gadolinium oxysulfide is a scintillator material that generates fluorescence under the action of x-rays. The fluorescence is collected by a photodiode to generate an electrical signal, which is also read by the TFT later. For a deeper understanding of flat panel detectors, please call +86 15628738108.
