1. An image processing system, comprising:
at least one processor in communication with memory, the at least one processor configured to:
receive a projection image from a plurality of projection images of a movable object acquired along a plurality of different directions by an imaging apparatus, the plurality of projection images defined in a projection domain spanned by a radiation sensitive surface of a detector of the imaging apparatus;
determine a decision of whether the projection image is corrupted by motion of the movable object during acquisition based on (i) a consistency measure in relation to an imaging geometry of the imaging apparatus and (ii) an operation in the projection domain; and
reconstruct an image, including cross-sectional information of the movable object, based on the decision.
