Figure 2
AFN synthesized projection data evaluated in the forms of (a) sinogram (data are missing in both the view angle and detector width dimensions), (b) acquired projection view demonstrating that the data are incomplete in the detector dimension, and (c) unacquired projection view in between 135° to 225°. Projection at 180° is shown here (see Fig. 1b) demonstrating that the data are also incomplete in the view angle dimension. AFN can fully inpaint the sinogram from the incomplete sinogram and only yields high uncertainties outside the anatomical region. In the acquired projection view (b), data are partially truncated on the left. AFN outputs visually similar projections as the reference. (c) No data are acquired at 180°. In addition, this projection view yields the highest uncertainties since data are most scarce here. Nevertheless, AFN is able to generate a high-fidelity projection view except yielding large errors outside the anatomical region.
