Lifespan of flat panel detectors

DR flat panel detector is very important in radiology imaging. Its development process is from film cassette to fluorescent screen and then to DR flat panel detector. At present, DR flat panel detector mainly uses materials such as amorphous selenium and amorphous silicon.
At present, due to the influence of raw materials, the life of DR flat panel detectors is 3-5 years under normal circumstances. Most manufacturers have a warranty of 3 years for flat panel detectors. Over 3 years due to the etching effect of amorphous silicon, resulting in flat panel detectors that exceed 3 years. Artifacts will be generated, and the normal images will gradually be imaged. Currently, there is no way to repair them. We can only wait for the advancement of technology to find better materials and increase the life of the flat panel detector.
