Initial experiences with radiation planning of combined teletherapy and brachytherapy of gynecologic tumors using CT tomograms]

Dose distributions of a combination from telecobalt-arc-therapy and afterloading-therapy for radiation therapy of gynecological cancers were calculated, using a computer program developed in our institute. Taking as a basis CT-scans the bone structures were taken into consideration like inhomogeneities. Conclusions about the individual dose on sensitive organs into the irradiated area like bladder and rectum become possible. The influence of changing parameters such like distance of axis of arc-therapy can be shown clearly.
