Figure 7

Illustration of the accuracy of fetal brain tissue segmentation in a subject of 30.6 weeks of GA on (a) an axial slice from the SR reconstruction. Comparison of (b) the reference manual annotations, (c) the segmentation results obtained when performing extensive standard data augmentation on the clinical SR reconstructions (configuration (E), C15/S0), (d) the segmentation results obtained by the configuration (D) that complements this original dataset with fifteen additional simulated subjects (C15/S15), overlaid on the SR image. The segmentation of the cortex especially looks more accurate in (d), with an increased sensitivity to folding as highlighted by the white arrows.
