Quasi-3D iterative reconstructionMS33

Slice-based visualization is a common analysis tool for 3D tomographic reconstructions. Conventionally, this requires a full volume, whereas a quasi-3D approach is to only reconstruct those slices that are currently of interest. Direct algorithms such as FBP and FDK are local in that they can reconstruct arbitrary slices efficiently. In contrast, iterative algorithms are harder to restrict to slices. We discuss approaches to tackle this problem, which is closely related to region of interest tomography.
