Abstract
This article presents an improved configuration for fitting the
radial dose functions of sealed 192Ir #brachytherapy sources. The
proposed functions allow for precise fitting of #radial dose function in
the range of 0.5 20 cm. The maximum deviations between fitting data and
Monte Carlo modeling data do not exceed 0.6%, while average deviations
are in the order of 0.1%. The fitting coefficients for the proposed
functions are specified for 11 sources from different manufacturers. The
proposed functions could be used in #treatment planning systems for more
accurate calculation of the dose distributions around the sources using
a wide range of data according to TG-43 #dosimetry protocol.
