Decreased 3D observer variation with matched CT-MRI, for target delineation in Nasopharynx cancer
PURPOSE To determine the variation in target delineation of nasopharyngeal carcinoma and the impact of measures to minimize this variation. MATERIALS AND METHODS For ten nasopharyngeal cancer patients, ten observers each delineated the Clinical Target Volume (CTV) and the CTV elective. After 3D analysis of the delineated volumes, a second delineation was performed. This implied improved delin...

Glioblastoma growth modeling for radiotherapy target delineation
Radiotherapy treatment planning requires a localization of the tumor within the patient. This is challenging to accomplish for microscopic infiltrative spread of disease that is not visible on current imaging modalities. Prime examples for infiltrative tumors are gliomas. With the help of mathematical models, common growth characteristics of gliomas, which are known from histopathological studi...
