Selection of calculation methods for the analysis of absorbed depth-dose distributions of electron beams

摘要

The work is dedicated to comparison methods of processing the results of measurements of the absorbed depth-dose distributions (DDD) of the electron radiation to determine the practical range of electrons. The sets of test data were obtained by modeling the DDD with use Monte Carlo method. The accuracy of the calculation method is determined by the mean square error of processing results the sets of test data. In the paper it was performed the comparison of computational methods of processing the measurement results that differs in the sizes of the array of data being processed and types of functions which use for approximation the data. Comparison the accuracy methods is base for the recommendations on the selection of computational methods for determining the practical range of electrons for computational dosimetry of electron radiation.
