1. A method for correcting saturation in at least one saturated ray comprising:
identifying a saturated ray corresponding to a first ray of a radiation source received at a radiation detector after passing through a reference point during a current view of the radiation detector and saturates a pixel of the radiation detector;
identifying at least one non-saturated ray corresponding to a second ray of the radiation source received at the radiation detector after passing through the reference point during a previous view of the radiation detector and does not saturate a pixel of the radiation detector or a third ray of the radiation source received at the radiation detector after passing through the reference point during a next view of the radiation detector and does not saturate a pixel of the radiation detector, wherein:
each of the previous view of the radiation detector and the next view of the radiation detector is adjacent to the current view; and
the radiation source has a first energy for the current view and a second energy for the previous view and the next view, the second energy being different than the first energy; and
responsive to the identifying, adjusting a value for the saturated ray based on a value of the at least one non-saturated ray.
