Flat Panels

Flat Panel overview

Flat panel sensors (FPS) are X-ray imaging modules which utilise a large area CMOS image sensor.

Flat panel sensors employ an indirect X-ray detection method that converts X-rays into visible light using a scintillator and a photodiode array detecting that light. This method requires photodiodes with a spectral response which matches the peak wavelength and spectral range of the scintillator emission.

  • There are two “scintillator-to-photodiode” coupling methods:
  • One method uses an FSP (flipped scintillator plate), which is a glass plate on which the scintillator is deposited, and the scintillator side of the FSP is attached in close contact with the photodiode.
  • Direct deposition of scintillator on to the photodiode.
  • The other method is deposition of the scintillator on to a Fibre Optic Plate (FOP) which is then placed directly on the photodiode array active area.

The flat panel sensor can capture distortion free high definition digital images. The thin profile and light weight make the flat panel sensors easy to install into various analysis equipment.

Flat panel sensors are now widely used in a variety of X-ray imaging systems and can be selected according to the application.
