Figure 2From: Comparison of direct machine parameter optimization versus fluence optimization with sequential sequencing in IMRT of hypopharyngeal carcinomaComparison of the DVH of the plans optimized with IM and DSS for one of the patients. The DVH of the PTV show a better target coverage and homogeneity for the plan optimized with DSS. The DVH of the parotids illustrates the compliance to the DVO of both plans, indicated by the purple arrow.Back to article page
