foszforlemeztechnológiával

Foszforlemezte is a term that appears to be a misspelling or a less common variant of a Hungarian word. The most likely intended word is "foszforlemez," which translates to "phosphor plate" in English.

Phosphor plates are a crucial component in computed radiography (CR) systems, a type of digital medical imaging technology. These plates are coated with a photostimulable phosphor material. When exposed to X-rays, the phosphor crystals store the energy of the X-ray photons in a metastable state.

To retrieve the image data, the exposed phosphor plate is scanned by a laser. The laser light excites the stored energy in the phosphor crystals, causing them to release light. This emitted light is then detected by a photomultiplier tube, converted into an electrical signal, and processed by a computer to form a digital radiographic image.

Phosphor plates are reusable and are erased by exposure to intense light after each use, allowing them to be re-exposed for subsequent imaging. This technology represented a significant advancement over traditional film-screen radiography, offering digital image manipulation, storage, and transmission capabilities. While newer flat-panel detector (FPD) technologies are now more prevalent in some applications, phosphor plates remain in use in many CR systems worldwide due to their cost-effectiveness and image quality.
