Relations between scatter factor, quality index and attenuation for x-ray beams

The relations between the attenuation factor, the normalized phantom scatter factor and the quality index are examined using a semiempirical formula for the dose on the central axis of an x-ray beam in water. The study is restricted to depths and field sizes sufficient for electron equilibrium. The...
