Proton beam therapy for locally advanced lung cancer: A review

Figure 1 Depth-dose comparisons of a single photon (X-ray) beam and a proton beam.

Figure 2 Dosimetric comparisons between photon [left (A, C, E) and proton right (B, D, F)] plans for a stage III lung cancer patient. Radiation doses shown as color washes warmer colors (red) represent higher doses compared to cooler colors (blue). The first pair of axial slices (A and B) are at a level superior to axial cuts C and D; It is apparent that more normal lung is irradiated on the left than the right; E and F are coronal cuts with dosimetry.
