[0043] The technical core of DR is the flat panel detector 700. The flat panel detector 700 is a sophisticated and expensive device that plays a decisive role in imaging quality. Familiarity with the performance indicators of the detector will help us improve imaging quality and reduce X-ray radiation dose.

[0044] Flat panel detector 700: According to the detector type, the DR system is mainly divided into amorphous silicon flat panel DR, amorphous selenium flat panel DR and CCDDR.

[0045] The indirect conversion flat panel detector 700 generally operates in two steps. First, the scintillating crystal coating converts X-ray energy into visible light. Second, the TFT, CD, or CMOS converts the visible light into an electrical signal. Because visible light scatters during this process, spatial resolution is affected.

[0046] Direct Conversion Flat Panel Detector 700: Primarily composed of amorphous selenium (a-Se) thin film transistors (TFTs). Incident X-rays generate electron-hole pairs in the a-Se layer. Under an applied bias electric field, the electrons and holes migrate in opposite directions, forming a current. This current forms a stored charge in the thin film transistors. The amount of stored charge in each transistor corresponds to the incident X-ray dose. A readout circuit can determine the charge at each point, and thus the X-ray dose at each point. Because amorphous selenium does not generate visible light and is not affected by scattered radiation, relatively high spatial resolution can be achieved.

The flat panel detector 700 further includes a wire harness 710 and a wire harness connector 720 for connecting to the outside. Reference numeral 730 is a wire harness fixing seat.
