Cont. C) Screenshots showing loading patterns, optimization techniques, isodose volumes, and cumulative and differential dose volume histogram generated after ‘manual dwell weights/time’ optimization using Fletcher tandem ovoid applicators. D) Although the loading patterns and optimization techniques are similar to Fletcher applicator as in Figure 2C, the 100% isodose is narrower and thinner, and dose delivered to contoured volumes are lower after using ring applicator
