Scintillator CsI 17*17 X-ray flat panel detectors

There are two main performance indicators for evaluating the imaging quality of X-ray flat panel detectors: quantum detection efficiency and spatial resolution. DQ E determines the ability of the flat panel detector to distinguish the density difference of different tissues; and the spatial resolution determines the ability to distinguish the fine structure of the tissue. The imaging capabilities of flat panel detectors can be evaluated by examining DQ E and spatial resolution.

In the indirect conversion X-ray flat panel detector, there are two main factors that affect DQE: the coating of the scintillator and the transistor that converts visible light into electrical signals.
