Caesium Iodide scintillator with column-like micro-structures that preserve image quality; intercepts the X-ray beam and converts it into visible light. The Fibre Optics Plate collimates the radiation onto the sensor and protects it against X-ray penetration. The CMOS acquisition device and the electronics convert the light into a high definition digital image
Diameter of a fiber strand / Distance between fiber centering
The numerical aperture, or NA, defines the angle of acceptance—beyond which light is lost out the sides of the fiber. The greater the NA of the fiber, the better the light transmission of the fiber.
The larger the N·A is, the

In addition to the mono fiber elements, a second fiber is used in the construction of the multi fiber. Extra-mural absorption (EMA)fibers are special black absorbing fibers, inserted between (or in place of) mono fibers, which will absorb stray (scat-tered) light in the fiber optic material.
The transmitting qlass in a fiber optic wave guide. The core has a higher index of refraction than the cladding.
The outer layer of glass in a fiber optic wave quide. The claddinc has a lower index of refractior than the core.
The packing fraction is defined as the ratio of core area to total area in the cross section of a fiber.
Transmission are used to
quantitatively describe the optical
fiber's light transmission capacity,
which is the ratio of the outgoing
luminous flux to the incoming
The greater the transmittance
is, the clearer the imaging will
