Figure 7
Diagram showing the steps of the virtual strategy (ADMP-V). (i) Reconstruction with FBP-E. (ii) Zero-out all pixels [\notin] FOV. (iii) Forward projection to obtain the virtual sinogram ([m_{\rm{v}}] = [n\pi/2]). (iv) The virtual sinogram is used as input for ADMP. The [\alpha^{{\rm{(an)}}}]-padding used for FBP-E is coloured in light blue, whereas the [\alpha^{{\rm{(int)}}}]-padding inside ADMP is coloured in light red.
