Error maps of the reconstruction results of in vivo experimental dataset. (a1)-(a4) represent the error maps corresponding to the reconstruction results of the DAS method in limited-view cases of 120°, 105°, 80° and 60°, respectively. (b1)-(b4) are the error maps corresponding to the reconstruction results of the U-Net method in limited-view cases of 120°, 105°, 80° and 60°, respectively. (c1)-(c4) show the error maps corresponding to the reconstruction results of the FS-DM method in limited-view cases of 120°, 105°, 80° and 60°, respectively. (d1)-(d4) are the error maps corresponding to the reconstruction results of the proposed method in limited-view cases of 120°, 105°, 80° and 60°, respectively. (a5)-(d5) represent the error maps corresponding to the ground truth. Ours, the approach utilizing multi-scale diffusion models; FS-DM, a diffusion model trained using the fully-sampled sinogram dataset; GT, ground truth.
