FIELD: medicine, in particular, radiotherapy. ^ SUBSTANCE: during irradiation of oncology patients on cobalt distance apparatuses dose field is formed by injecting topographic-anatomic information of patient into dose planning system and generating with its consideration of main dose field on basis of results of calculations of main dose field, dose deficiency area is located within limits of target and iso-centers of additional dose fields are positioned therein, while width of radiation beams, generating additional dose fields, is less than width of beam of main dose fields 1,5-2,5 times, while value of dose of main field is 0,7-0,85 of resulting dose within limits of target. ^ EFFECT: possible generation of dose field with minimal possible dose change on target while simultaneously decreasing radiation loads on normal tissues and skin. ^ 2 dwg, 1 ex |
