Figure 1From: Comparison of direct machine parameter optimization versus fluence optimization with sequential sequencing in IMRT of hypopharyngeal carcinomaIsodoses of the plans optimized with a) IM and b) DSS for one of the patients in two representative transversal slices and the central sagittal plane. The better target coverage is visible particularly in the region around the right parotis. The red arrows point out regions of underdosage in the plan optimized with IM.Back to article page
