Reconstruction gamma maps (3%/3 mm local) of the reconstructed light distributions using the profile-based method with correction factor. (a) 2D gamma maps of the single beam model at x = 0 mm and (b) around the Bragg peak at z = 172 mm. (c) 2D gamma maps of the prostate treatment model at x = 6 mm and (d) around the Bragg peak at z = 172 mm. The following colour scheme was used: Green - passing gamma requirement, light grey – low output region below threshold, red – failing gamma requirement with positive difference in light output, and blue – failing gamma requirement with negative difference in light output. The values represented by the colour bars on the right are the gamma values.
