Figure 2

Importance of long-range dose calculation. The figure shows ΔD=(Dshort range-Dfull dose)∕DRx for the spinal cord Dmax (black) and mean lung dose (gray) for each patient using the ROCO intensities. In order to get accurate results from ROCO, the dose calculation for each PCA mode used by the constrained optimization must be performed with the full long-range dose kernel.
