[A low-cost localization technique for high-dose-rate afterloading applicators].

For radiation safety control radiotherapy today needs a method to check the correct position of a HDR-gynecological applicator before afterloading treatment. At the university clinic in Essen, West Germany, a surgical c-X-ray plant was used for the construction of an orthogonal X-ray-photograph plant, which combines illumination and photographs as localisation technique.
