1. An imaging system, comprising: a first and a second set of imaging detectors acquiring imaging data indicative of a patient over a length of time, the plurality of imaging detectors being arranged proximate the patient and remaining in a fixed position with respect to the patient, wherein the first set of imaging detectors are interleaved with the second set of imaging detectors; and a processor receiving the imaging data, the processor assigning the imaging data into subsets based on at least one of a detector number and a pixel location, the processor iteratively processing the sub-sets, wherein iteratively processing the sub-sets comprises iteratively reconstructing at least one of the sub-sets.
