[Soft- and hardware support for the setup for computer tracking of radiation teletherapy].

A hard and soft ware computer assisted complex has been worked out for gamma-beam therapy. The complex included all radiotherapeutic units, including a Siemens program controlled betatron with an energy of 42 MEV computer ES-1022, a Medigraf system of the processing of graphic information, a Mars-256 system for control over the homogeneity of distribution of dose rate on the field of irradiation and a package of mathematical programs to select a plan of irradiation of various tumor sites. The prospects of the utilization of such complexes in the dosimetric support of radiation therapy are discussed.

[Computerized program for calculating the dose distribution generated by intracavitary linear sources of gamma radiation].

One can achieve a high precision in the dosing of a session of intracavitary radiotherapy by rapid computerization of the treatment time that is necessary for obtaining a certain dose in a pathological focus taking account of an actual location of radiation sources in the process of irradiation. The authors have developed an algorithm and drawn up a program for computer ES-1022 to calculate a dose rate in any point of an irradiated volume from the system of gamma-radiation sources oriented arbitrarily in space. As part of a hard- and soft ware dosimetric complex, the above program provides for the calculation of the treatment time by a set dose; the time is necessary for supplying this dose to a tumor focus taking account of an actual location of radiation sources during a session of irradiation.
