Table 1.
The dosimetric comparison for the IMPT versus the VMAT plans.
Fig 1.
Dose distribution for the breast with and without regional nodes for volumetric modulated arc therapy (right side) versus intensity modulated proton therapy (left side).
A Right breast and regional nodes. B Left breast and reginal lymph nodes. The axial, sagittal, and coronal images are presented from top to bottom, respectively.
Fig 2.
The mean dose to organs at risk with 95% confidence intervals, comparing proton (intensity modulated proton therapy, represented by blue bars) and photon (volumetric modulated arc therapy, represented by orange bars) for each subgroup: left breast with regional nodes, left breast only, right breast with regional nodes, and right breast only.
A = ipsilateral lung, B = contralateral lung, C = heart, D = esophagus, E = thyroid, and F = liver (shown only for the right-sided subgroups).
