Results:

All ten cases passed all the acceptance criteria (see figure 2) except for one (with tumor motion of 1.5cm), which marginally failed one parameter, by a clinically insignificant amount (D1% = 72.65Gy for a tolerance of 72.6Gy). The case was reoptimized with volumetric repainting and all the dosimetric parameters passed the acceptance criteria.
