In comparison standard Ring, use made increase coverage prescribed from 69.2 95.5 %. This led per course radiation therapy 70.4 85.4 Gy. Twelve plans 3 patients analyzed different fractionation schemes. all three cases, was dose, total target, more than 85 has been successfully applied N. Alexandrov National Cancer Centre womb.
