X-Ray Detectors

X-ray detectors use scintillators and arrays of silicon photodiodes or semiconductors to detect the X-ray region of the electromagnetic spectrum.

Scintillators change x-rays into visible light and electrons, which are read by a thin layer of glass and silicon, a device known as a thin-film transistor (TFT) array. Scintillator-based indirect flat panel detectors (FPDs) are in common in medical, veterinary and industrial applications. Semiconductor detectors directly convert x-ray photons into an electrical charge to create a digital picture.
