Comparison of DVFs solved by the SMEIR-Bio and the SMEIR-Unet techniques (a); Comparison of the corresponding motion-compensated CBCT images reconstructed by the SMEIR-Bio and the SMEIR-Unet techniques (b). The DVFs were from the same patient case as Fig. 6, and shown at the same slice locations. SMEIR: Simultaneous motion estimation and image reconstruction; CBCT: Cone-beam computed tomography; SMEIR-Bio: Biomechanical modeling-guided SMEIR; SMEIR-Unet: SMEIR with U-net based DVF fine-tuning; DVF: Deformation-vector-field
