title: [Errors in the presentation of topometric data in radiotherapy planning systems].
abstract: Computer-aided simulation was used to assess the accuracy of calculating the effective radiological thickness in the system for planning radiation therapy while presenting anatomical data as a set of organ contours with various density areas. The data were compared with tomographic findings and the dependences of a calculation error upon the provision of a detailed specimen presentation were obtained. The effect of the complexity of a set of contours was studied and a dose error was calculated for typical therapy 60Co radiation beam.
