What device converts X-rays into light for imaging?

The device that converts X-rays into light for imaging is a charge-coupled device (CCD). CCDs are widely used in various imaging applications, including X-ray imaging, because they are highly sensitive and can effectively convert incoming X-ray photons into visible light. This conversion process occurs through a photoconductive layer that absorbs X-rays, generating electron-hole pairs which are then transferred through the CCD, eventually leading to light emission that can be captured for imaging.

In the context of medical imaging, the ability of CCDs to produce clear and detailed images from X-ray data significantly enhances diagnostic capabilities. Their sensitivity and efficiency allow for lower doses of radiation to be used while still obtaining high-quality images.

Other devices mentioned, like X-ray film, do not directly convert X-rays into light; instead, they capture images through chemical reactions to X-ray exposure. Photomultiplier tubes are used for detecting light, not specifically converting X-rays, and cine cameras are designed for capturing moving images and are not specialized for X-ray imaging. Therefore, the characteristics and functionality of CCDs make them the appropriate choice for converting X-rays into light in imaging applications.
