Fig. 6From: The evaluation of a hybrid biomechanical deformable registration method on a multistage physical phantom with reproducible deformationImage fusion for DIR between Phase 0 & 10: a before DIR; IM-DIR with (b) CT, e MR, h Masked MR; BM-DIR with (c) CT, f MR, i Masked MR; color rendering motion magnitude of (d) CT, g MR, j Masked MR. The green arrow points to sub-optimal matching of urethra structure after DIRBack to article page
