The DR flat panel detector is used for a certain number of years (usually three to five 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 physical properties of amorphous silicon oxide transistors are unstable and decay quickly under light. Therefore, large areas of dead pixels appear every day. When the dead pixels reach a certain amount, it cannot be repaired, and the entire flat panel detector needs to be replaced. In fact, as of today, no flat panel detector can be used normally for more than five years.
