Radiographic sensitivity improved by optimized high resolution X-ray detector design
Paper i proceeding, 2007
A compact imaging detector, based on scintillation fiber optics, has been used for high
resolution industrial radiography since 1996. This type of imaging detectors have proven
to give superior performance compared to fine grained industrial x-ray film in terms of
detection efficiency and spatial resolution.
The objective of this paper is to show that the radiographic sensitivity can be improved
First, the detection process has been studied by Monte-Carlo simulations and the result
shows that the radiation is detected in a very narrow range from the axis of the primary
Secondary, Monte-Carlo simulations shows that a bent fiber optic image conduit can
eliminate radiation induced noise in the CCD almost completely and reduce the depth of
the detector to less then 100 mm.
