This paper describes a supporting tool for medical doctors, providing the automatic definition of radiation volumes (planning target volume, PTV) for conformal radiotherapy computed on detected tumor areas (gross tumor volume, GTV) within radiographic images. First, the recognized brain tumor is geometrically reconstructed and visualized in three-dimensional space. Then, the respective growth d...
