The deformable registrations performed in this study. Registrations were performed in both CT-to-MR and MR-to-CT directions to test for inverse consistency, as well as both directly (multi-modal) and with a synthetic CT bridge (synthetic mono-modal). The DVF from CTsynth→ CTnon-aligned was applied to the MR to generate a deformed MR image. The non-aligned CT was also registered to the aligned CT (and vice versa) to see an approximate best-case synthetic mono-modal registration.
