[A system of automated radiation treatment of malignant tumors using optimal irradiation programs]

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.
