How does the structural material of the output phosphor in an X-ray image intensifier affect light output and image quality?

The structural material of the output phosphor in an X-ray image intensifier significantly influences light output and image quality. The output phosphor is responsible for converting the X-ray signal into visible light, which is then detected and used to create the final image. CsI (cesium iodide) and Gd2O2S (gadolinium oxysulfide) are common materials for output phosphors.

CsI has higher atomic number and density, leading to increased X-ray absorption and improved detective quantum efficiency (DQE). This results in higher light output and enhanced image quality. Gd2O2S, while widely used, has lower X-ray absorption efficiency compared to CsI.

Therefore, the choice of output phosphor material directly impacts the overall sensitivity, contrast, and resolution of the X-ray image intensifier, influencing the diagnostic quality of the final images in medical imaging applications. We are a manufacturer of X-ray machines and their accessories.
