Avoiding local optima of the joint entropy prior in limited view tomography using a multiresolution scheme

Abstract

The incorporation of anatomical reference images into limited view transmission tomography has been attempted previously by using the joint entropy prior. However, this prior has been found to be sensitive to local optima. Here, we propose to increase robustness to local optima by using a multiresolution optimisation scheme. To our knowledge, this is the… (More)
