Abstract
During a radiation treatment plan optimization loop, a control circuit can conduct a dosimetric optimization iteration to yield a dosimetric-based plan result and then conduct a non-dosimetric optimization iteration to yield a non-dosimetric-based plan result. The control circuit can then assess the dosimetric-based plan result and the non-dosimetric-based plan result to yield a convergence assessment result. The latter can then be taken into account when determining whether to conclude continued radiation treatment plan optimization loops.
