1. A system for iterative image reconstruction, comprising:
a non-transitory memory device for storing computer-readable program code; and
a processor in communication with the non-transitory memory device, the processor being operative with the computer-readable program code to perform operations including
receiving image data and anatomical data of a region of interest,
generating zonal information based on the anatomical data, wherein the zonal information includes at least one zone-function that defines at least one smoothed zone of the anatomical data,
performing the iterative image reconstruction based on the image data to generate reconstructed image data,
determining one or more image quality metrics for the reconstructed image data using the zonal information, wherein the one or more image quality metrics are based on the at least one zone-function and quantitatively measure quality of the reconstructed image data within or at a boundary of the at least one smoothed zone,
in response to the one or more image quality metrics satisfying a stop-criterion, terminating the iterative image reconstruction, and
outputting a final image generated by the iterative image reconstruction.
