title: [Mathematical models in clinical radiobiology and optimization of the radiotherapy of tumors].
abstract: A mathematical model was developed in the system of tumor-normal tissues. It reflected the main radiobiological factors and regularities of tumor growth kinetics: heterogeneity of cell populations with relation to radiosensitivity and a tendency to proliferation, the effects of reoxygenation. Using a package of RADON applied programs optimum irradiation regimens were obtained simultaneously for single doses and intervals of interfractional recovery. Optimum irradiation regimens were shown to be dynamic fractionation of a total dose and the entire period of treatment.
