Abstract :
Presents an overview of two developments in tomography: design of optimum scan patterns for time-varying objects; and an efficient iterative edge-preserving algorithm for limited-angle data. The first development involves the introduction of a new problem definition and changing the “rules of the game” by unconventional acquisition formats. It also employ the mathematical tools of lattice theory, which have seen relatively little use in this area. The second development, on the other hand, addresses a classical and long standing problem, by a combination of more rigorous analysis and modeling with some heuristic twists
