Figure 5

The segmentation results on MR images. The segmented ovarian tumor regions by U-net++ network (the red line) and operator (the green line, ground truth) are shown on coronal T2WI (left column), T2WI sagittal (middle column), and T1WI (right column). The top row represents precise segmentation cases with Dice values over 0.9 and the bottom row represents poor segmentation cases with Dice values less than 0.7.
