[Methodologic studies on the optimization of the 60Co-teletherapy in combination with high dosage brachytherapy of cervix carcinoma].
After dosimetric recording of the radium implants being in use at the radiological department of the gynecological clinics at Vienna, an attempt is made for the adaptation of cobalt-60 teletherapy to brachytherapy generally applied here and utilizing relatively high dosage. A biaxial, bisegmental small-angle rotation about two cranially convergent axes, combined with the radium doses, yields a relatively well equilibrated load on the parametrial tissue and on the essential areas of the lymph flow. The dose distribution is shown by transversal as well as by frontal sectional planes. If deviations of the position of the radium implants, always possible in an individual case, are verified by localization imaging, asymmetrical dose distributions can be calculated by a computer and compensated by means of different loads to the axes of rotation.
