Investigations on creation of dose distributions atlas for multifield and rotational irradiation for gamma therapy apparatus

Results of work have been presented on creating the atlas of isodose maps which are the main guiding material for planning irradiation seance. Dose standardization has been described in composing the maps of dose distributions for manyfield and rotary irradiation. Algorithm has been obtained for dose calculation in any point of irradiated media and general laws of dose distributions have been revealed. Under manyfield and rotary irradiation the dose calculation error in the region, limited by the sphere radius equal to half of the field size does not exceed +- 7%, and outside of this region does not exceed +- 10%
