Fig. 6: Dose profiles of the full and partial arc treatments delivered with a 5 cm SpeleoFilter (center row) compared against multifield IMPT treatments (left row).
From: Range-compensated pencil beam scanning proton Arc therapy: a feasibility study
The number of energy changes are listed in the top corner for each delivery. Dose volume histograms are shown for the four-field IMPT against the full-arc (top row), three-field IMPT against a half-arc (center row), and the two-field IMPT against a quarter arc (bottom row). Regions of interest are shown for the skin (green), pencil beam scanning target volume (Target, red), the adjacent 10 mm of surrounding normal tissue (Ring 10 mm, black), and the body volume (blue).
