TABLE V.

Ablation study of designed modules in data augmentation by synthesis is accessed by dice score. Ablation study of designed modules in term of synthesis quality is accessed by pixel accuracy. The reported value is pixel accuracy in the lesion region (i.e. the union of edema, cavity, and tumor) as percent (%). A synthesized pixel was counted correct if the absolute difference was within 16 of the ground truth intensity value.
