Dental film scanner captures X-ray images on a special PSP plate coated with phosphor, which stores the X-ray energy as a latent image.
When the plate is scanned with a laser, it emits light proportional to the stored energy. This light is detected and converted into digital data, producing a high-quality digital image for diagnostic use.
The plate can then be erased with a bright light and reused, offering an efficient, reusable alternative to traditional film-based radiography.
