Reconstructions of real CT data experiments. First and second columns from left to right are results of (a) Gao’s method and (b) the distance-driven model, both with GPU acceleration. Images from top to bottom row show the results of median sagittal, central coronal, and central transverse sections. The red rectangle shows ROI used for SNR calculation.
