[Computed tomographic localization of the uterus for optimization of primary combined radiotherapy of inoperable cervix cancer].

The authors present the technique of CT reconstruction of the shape of the uterus in topograms of the pelvic region. The treatment scheme of combined endocavitary and percutaneous radiotherapy of uterine cervix carcinomas can be improved by means of the described method. The reliability of this method is compared to that of radiotherapy planning based on measuring radiography. Modifications of the position of the uterus obtained by endocavitary inserts proved to be relevant if the endocavitary regions exposed to high doses are left out from percutaneous therapy.
