Abstract
Stereotactic radiation therapy in the hypofractionation mode is a method in which high doses of ionizing radiation (more than 3 Gy per fraction) are delivered in a small number of fractions (from 2 to 5). Treatment and the process of preparation for it are carried out using special fixing devices, dosimetric planning techniques of high conformity, with control of the treatment position using x-ray imaging. which makes it possible to ensure the required irradiation accuracy. The advantages are a shorter course of treatment compared to standard fractionation, a high biologically effective dose, a reduced effect of tumor repopulation, greater efficiency under hypoxic conditions, and satisfactory results when irradiating radioresistant tumors. The article presents clinical cases of the use of hypofractionation modes on the Halcyon elite linear accelerator.
