The technical core of DR is a Flat Panel Detector (FPD), which is a precise and expensive device that plays a decisive role in the imaging quality, and the familiar performance indexes of the detector help us to improve the imaging quality and reduce the X-ray radiation dose.
Under the condition that the X-ray source and the FPD are communicated (wired or wireless), the exposure mode is that the X-ray source actively sends an exposure request signal to the FPD, then the FPD completes residual charge clearing line by line under the driving of the control module, the FPD sends an exposure request signal to the X-ray source after the clearing is completed to prepare for exposure, and the X-ray source immediately starts exposure after receiving the exposure request signal of the FPD. After exposure, FPD starts to collect electric signal proportional to X-ray irradiation intensity, and imaging is carried out after signal processing. Under the condition of communication, the fine control of the time sequence can obtain good image quality.
In different types of FPDs, the exposure request signal (synchronization signal) sent by the FPD to the X-ray source is different, and it is common practice to synchronize the X-ray source and the FPD in a fixed manner based on the synchronization signal.
However, different types of flat panel detectors are different from the X-ray source synchronous signals, and the adoption of fixed-place type synchronization can cause that different flat panel detectors cannot be well compatible.
