Figure 1

Schematic diagram for DVH representation to ease comparison of the fraction DVH with the respective planning DVH for three exemplary curve progressions: The blue curve is representing an arbitrary organ at risk, the pink and red curves target volumes. PLN: planned DVH. Fx: fraction x. A positive curve progression (e.g. indicated by blue arrows) implies that more volume of this organ at risk, e.g. spinal cord, receives the respective dose and vice versa.
