Abstract
A source of X-rays encompassing a rotating target is provided with a detector of X-rays located outside a port of a housing of the source and positioned at or near a tangent line to the radiating surface for observing variations in the radiation intensity due to rotation of the target, the variations being pronounced due to the heel effect of the radiation pattern. In one embodiment, the X-ray detector employs a scintillation material and is coupled by a light pipe to a photodetector which is removed from the path of the radiation and detects scintillations of the X-ray detector. Alternatively, the photodetector and light pipe may be deleted by the use of a detector of germanium, silicon or an ion chamber which converts X-ray photons directly to an electric current.
