Table 3.

Quantitative comparison of CBCT-MRI registration results using DSC and ASD(mm). Best and second best results are marked in red and blue, respectively. Underline means supervised trained model using ground truth segmentation on the target domain. IMG-BSpline and IMG-Affine mean intensity-based BSpline registration and affine registration, respectively. ‘CT’-IMG-BSpline means intensity-based BSpline registration based on CT images translated from CBCT and MR using APA-Net.
