The current main drawback of this radiotherapy is the insufficient documentation of the applied radiation and the lack of a possibility for an individual treatment planning. This work presents a system that is a common development of Fraunhofer IGD, Sädtische Klinik Offenbach and MedCom GmbH which offers a possibility for supervision of the placement of the irradiation flabs through interactive navigation in CT data acquired from the patient, the creation of a documentation of the applied isodose as well as the possibility for an individual treatment planning.enIntra Operative NavigationIntra Operative Radio Therapyvolume rendering006conference paper
