Table 1.

Quantitative comparison of CBCT and MRI segmentation results using DSC and ASD(mm). Best results are marked in red. Underline means supervised training with ground truth segmentation on the target domain, i.e. CBCT or MRI segmentation. The negative sign ‘-’ means without the corresponding loss component in our APA2Seg-Net.
