Fig. 10From: Sparse-view tomography via displacement function interpolationFBP reconstruction using non-rigid deformation interpolated sinogram with old angular gap = 0.9° and new angular gap = 0.3° (1200 views over 360°). This result does not suffer from the rotation artifacts. Left image display window: [min, max]. Right image display window: [− 400, 400] HUBack to article page
