Zusammenfassung

Der vorliegende Artikel soll einen Überblick über den physikalisch-technischen Aspekt des Zielvolumenkonzeptes der Strahlentherapie geben. Nach einer Einführung der Begrifflichkeiten im Zusammenhang mit dem Zielvolumen werden die beim Einbinden von funktionellen PET-Daten zur Definition des GTV auftretenden Probleme und Lösungen beschrieben sowie offene Fragen adressiert.

Abstract

The aim of this article is to give a short review over the physical-technical aspects of the target volume concept in radiotherapy. After an introduction of the target volume the problems and solutions are described when integrating functional data for the definition of the GTV are used. Finally, open questions are being addressed.
