The DR flat panel detector is the core component of the entire DR system, and it is also the most expensive component, which is a key factor in image imaging quality. In daily work, we must strictly follow the maintenance manual provided by the manufacturer to maintain the detector on a regular basis; be familiar with its principles and characteristics, and perform routine maintenance in order to extend its service life and ensure high-quality X-ray inspection images.
Under normal maintenance and maintenance, the service life of the DR flat panel detector is about 5 years. The DR flat panel detector is used for a certain number of years or after a certain number of exposures, the aging and damage of the DR flat panel detector is inevitable and inevitable.
The high maintenance cost of DR flat panel detectors is mainly due to the high integration of internal components, and the unstable physical properties of amorphous silicon oxide transistors, which decay quickly under light, so large areas of dead pixels appear every day. When the dead pixels reach a certain amount, it cannot be repaired, and the entire DR flat panel detector needs to be replaced.
