RESUMEN
A computerized system of optimum plans of radiotherapy (computer SM 1420) was developed for the first time in the USSR. The ROPLAN system was adapted to a dosimetric design of irradiation sessions for all radiotherapy units, manufactured in the USSR, and provides for modes of initialization, design, storage and collection of data for all radiotherapeutic methods.

A system of automated control Aspect-2 was developed for automation of gamma-beam therapy on units of the Rokus series. The system consists of the following hardware and software complexes: a complex of preirradiation preparation "Centrator-imitator"; a complex Accord for anatomotopographic data coding; a software complex and a gamma-therapeutic complex Rokus-AM. The Centrator-imitator and Rokus-AM complexes are fitted out with built-in microcomputers with specially developed systemic software. The Rokus-AM complex has automatic punch tape programmed control of 9 degrees of freedom of the gamma-unit and treatment table and ensures 5 modes of irradiation: positional, rotating, rotating-convergent, sectoral rotating-convergent and scanning.

The authors sum up their clinical experience in the implementation of optimized irradiation programs for tumors of different sites (the esophagus, lung, female genital organs, ear-nose-throat, rectum and urinary bladder) with the help of the first serial specimen of the system of automated control over irradiation--Altai-MT. The utilization of the system makes it possible to save time and avoid an error in the implementation of complex irradiation programs as well as to lower the exposure of medical personnel to radiation. Tumors with average and low radiosensitivity, biologically highly active and located in the vicinity of organs and tissues with a low limit of tolerance to ionising radiation were used as clinical models. Automated programs of irradiation meet the requirements of the conformity and homogeneity of a dose field within a focus of lesion, gradient conditions on the border with normal tissues, the minimization of radiation exposure in critical organs. The purpose of the automation of gamma-beam therapy of tumors is to unite within the common system automated information topometric units and a gamma-therapeutic computer controlled device.
