Table 4.
Estimated treatment time of the three plans by quadratic min., TV min., and the proposed method for the five clinical cases. The plans by the proposed method can save the estimated dose delivery time by about 10–30 s over the TV min. based plans, and about 30–80 s over the quadratic min. based plans.
