Principle of amorphous selenium X-ray flat panel detector

Do you know what an amorphous selenium X-ray flat panel detector? The computer directly restores the affected information to form an X-ray image. After all the charge information is read, the remaining residual charges are eliminated, and the entire collection device is returned to the initial state to wait for the next round of information collection.

Since amorphous selenium is a light-guiding material, it can directly generate electrical signals after receiving X-ray exposure, which fundamentally avoids the phenomenon of scattered light in the indirect conversion method, which leads to the reduction of the spatial resolution of the graph.

The direct conversion X-ray flat panel detector has the advantages of high airborne resolution, good image sharpness and high conversion efficiency due to its morphological structure, but due to its direct quasi-X-ray characteristics, the absorption efficiency of X is low. Therefore, the image quality cannot be well guaranteed under low-dose X-ray conditions. Since the direct X-ray flat panel detector is sensitive to X-rays by amorphous selenium, due to the temperature and sensitivity of selenium, the direct X-ray flat panel detector has certain restrictions on its environmental requirements. Our company specializes in the production of image intensifier TV systems. The products include image intensifiers, CCD cameras, image processors, monitors. The products are exported to Europe, America, Africa, and the Middle East, and are well received by customers from various countries. Vertical, mobile chest X-ray frame, various types of X-ray machine and its parts, if you have similar items, please call to discuss.
