Abstract

This thesis describes the results from measurements of the out-of-field dose in radiotherapy. The dose outside the treatment volume has been determined in a water phantom and an anthropomorphic phantom. Measurements were performed with linac photons, passively delivered protons, scanned protons, passively delivered carbon ions as well as scanned carbon ions. It was found that the use of charged particles for radiotherapy reduces the out-of-field dose by up to three orders of magnitude compared to conventional radiotherapy with photons.

Diese Arbeit beschreibt die Ergebnisse von Dosismessungen in der Strahlentherapie. Die Dosis außerhalb des Zielvolumens wurde für ein Wasserphantom und ein anthropomorphes Phantom bestimmt. Dabei wurden Messungen für Photonen, passiv modulierte Protonen, gescannte Protonen, passiv modulierte Kohlenstoffionen und gescannte Kohlenstoffionen durchgeführt. Die Messungen haben gezeigt, dass sich die Dosis außerhalb des Zielvolumens um bis zu drei Größenordnungen reduzieren lässt durch Verwendung von geladenen Teilchen anstelle von Photonen.German
