3D Analytic Cone-Beam Reconstruction for Multiaxial CT Acquisitions

Figure 12

Worst-case images from (a) 3rd generation CT system with 40 mm coverage, (b) 3rd generation CT system with 80 mm coverage, reconstructed using FDK with Parker weighting approach, (c) multi-axial acquisition CT system with 120 mm coverage, (d) multi-axial acquisition CT system with 160 mm coverage, reconstructed with slice substitution approach using FDK parker weighting slices, (e) multi-axial acquisition CT system with 120 mm coverage, and (f) multi-axial acquisition CT system with 160 mm coverage, reconstructed with cone-angle dependent weighting reconstruction. Grayscale: (−50 HU, 50 HU). Note that the worst-case slices for 3rd generation system are the slices located at the edge of scan FOV, and the worst-case slices for multi-axial acquisition system are the slices located in between two sources.
