Detector response and exposure control of the RadioVisioGraphy system (RVG 32000 ZHR)

摘要: Abstract The RadioVisioGraphy system (RVG 32000 ZHR) was studied with respect to some physical properties including the precision and linearity of exposure control detector response x-rays. x-ray unit found yield repetitive exposures that are precisely controlled by CCX timer. A “preheat” an “after exposure” period were noticed, their resulting measured. Two RVG detectors compared for responses differences between insignificant. However, inhomogeneous in both detectors; same exposure, central parts yielded lower pixel values than peripheral parts. calibration equation developed correct inhomogeneity.
