Validation test
Qualitative depictions of dose profiles generated by GammaPlan and by simulation appeared to be equivalent (Figure Dose profiles validating dose calculation accuracy of the simulation method used in the current study. Panels (a) and (b) illustrate planar isodose distributions from the GammaPlan and the simulation, respectively. Panels (c) and (d) illustrate equivalency of the vertical and horizontal dose profiles from GammaPlan (dashed line) and simulation (solid line)
