Abstract
Official abstract text for this publication.
Methods, systems, and non-transitory computer readable media for image reconstruction are presented. Measured data corresponding to a subject is received. A preliminary image update in a particular iteration is determined based on one or more image variables computed using at least a subset of the measured data in the particular iteration. Additionally, at least one momentum term is determined based on the one or more image variables computed in the particular iteration and/or one or more further image variables computed in one or more iterations preceding the particular iteration. Further, a subsequent image update is determined using the preliminary image update and the momentum term. The preliminary image update and/or the subsequent image update are iteratively computed for a plurality of iterations until one or more termination criteria are satisfied.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for image reconstruction, comprising: receiving measured data from an imaging system; determining a preliminary image update in a particular iteration of a plurality of iterations based on one or more current image variables computed using one or more subsets of the measured data in the particular iteration; determining at least one momentum term using the one or more current image variables computed in the particular iteration, one or mor…
