A computed tomography reconstruction method includes concurrently emitting radiation from at least two x-ray sources (14), switching the output state of each of the at least two x-ray sources (14) within a plurality of respective cross scatter sampling intervals (50, 52, 54, 56) and detecting with a corresponding one of the sets of detectors (24) cross scatter radiation emitted by the other at least two x-ray sources (14), wherein the cross scatter sampling intervals are angularly spaced over a plurality of frames to allow the at least two x-ray sources (14) to concurrently emit radiation throughout at least one frame, deriving scatter correction data for each set of detectors (24) from corresponding cross scatter samples, scatter correcting the projection data with corresponding scatter correction data, and reconstructing the scatter corrected projection data to generate at least one image.
