3D Analytic Cone-Beam Reconstruction for Multiaxial CT Acquisitions
Figure 3
The detector utilization of the FDK-based and TOM windowing reconstruction approaches. The area closed by red lines represents the actual acquired area of the detector for (a) multi-axial scan/line source CT, (b) line source CT curved collimator, and (c) multi-source inverse geometry CT. The area in blue represents the data required to reconstruct volume using TOM windowing approach. Note that TOM windowing has an advantage over FDK in detector utilization if data is acquired by the line-source CT with the collimator or the multi-source inverse geometry CT.
