title: [Computational methods for determining the mean tissue doses during x-ray procedures].
abstract: The Soviet and Finnish authors presented a short description of two computer methods to determine doses in the patients' organs. Based on the general principles, such as a semiempirical mathematical description of dose fields and a realistic anthropomorphous phantom, these methods differed significantly in the algorithms used and ways of solving specific problems. The comparison of these methods and calculated dose values with the results of experimental measurements on the phantom showed a good convergence of the results. The divergence of calculated and experimental data by the values of the mean absorbed doses in the organs did not exceed +/- 35%. The advantages and prospects of the use of the computer methods for the evaluation of doses received by patients, were demonstrated.
