A table of phantom scatter factors of photon beams as a function of the quality index and field size.
Phantom scatter factors, for square fields of various sizes, have been determined at a fixed reference depth of 10 cm, separately in different institutes, for a large number of linear accelerators under the auspices of the Netherlands Commission on Radiation Dosimetry. The method used for these measurements has been described in a previous paper. The present article describes the conversion of the measured values into a comprehensive and consistent data set, that gives the phantom scatter factor as a function of field size (from 4 cm up to 40 cm) and quality index (from 0.600 up to 0.800).
