FOS, ACS, ALS
OVERVIEW
The FOS is an X-ray imaging device making use of a fiber optic plate (FOP) coated with X-ray scintillation material. The fiber optic plate is an optical deviceconsisting of more than 50 million glass fibers of several microns in diameter, bundled parallel to one another. Compared to conventional phosphor screensusing adhesive, the FOS offers high sensitivity and high resolution, and allows real-time digital radiography when used while directly coupled to a commercially available CCD. The fiber optic plate used in the FOS has excellent X-ray absorption characteristics, so that X-rays which penetrate the X-ray scintillator and directly enter the CCD are minimized to less than 1%. This protects the CCD from device deterioration and from increased noise caused by X-ray irradiation, assuring a long CCD service life and maintaining high image quality.
ACS is an X-ray imaging device fabricated by coating high-resolution CsI(Tl) scintillator over the surface of a thin amorphous carbon substrate through which X-rays penetrate with a high S/N ratio. By coupling an ACS to a two-dimensional imaging device, a very thin X-ray imaging panel can be formed. Effective sizes currently available are from 14 x 14 mm to 440 x 440 mm.
