Radiology imaging equipment amorphous selenium X-ray flat panel detector

Do you know what an amorphous selenium X-ray flat panel detector is?
Since amorphous selenium is a light guide material, it can directly generate electrical signals after being irradiated by X-rays, which fundamentally avoids the phenomenon of light scattering in the indirect conversion method, thereby reducing the spatial resolution of the graphics.
The direct conversion X-ray flat panel detector has the advantages of high airborne resolution, good image clarity and high conversion efficiency due to its morphological structure. However, image quality cannot be guaranteed well under low-dose X-ray conditions. Since the direct X-ray flat panel detector is sensitive to X-rays of amorphous selenium, due to the temperature and sensitivity of selenium, the direct X-ray flat panel detector has certain restrictions on its environmental requirements.
