Information propagation in prior-image-based reconstruction

摘要

A framework, comprising techniques, process(es), device(s), system(s), combinations thereof, or the like, to analyze propagation of information in prior-image-based reconstruction by decomposing the estimation into distinct components supported by a current data acquisition and by a prior image. Such decomposition can quantify contributions from prior data and current data as a spatial map and/or can trace specific features in an image to a source of at least some of such features.

1. A method for evaluation of propagation of information in prior-image-based reconstruction, the method comprising:
providing an objective function, wherein the objective function comprises a second term representing a generalized image penalty that discourages roughness in the reconstruction through use of one selected from a group consisting of a gradient applied to an image volume, a sparsifying operator applied to an image volume, a combination thereof, or a p-norm metric; and decomposing the objective function into a first component dependent at least on current imaging data and a second component dependent at least on prior imaging data.
