摘要：
A system for constructing images representing a 4DCT sequence of an object from a plurality of projections taken from a plurality of angles with respect to the object and at a plurality of times, first portions of the object being less static than second portions of the object. The system may comprise a processor configured to: iteratively process projections of the plurality of projections for a plurality of groups, each group comprising projections collected while the first portions of the object are in corresponding locations, with each iteration comprising: reconstructing first image portions representing the first portions of the object, the reconstructing of each first image portion of the first image portions being based on projections in a respective group of the plurality of groups； and reconstructing the second image portion, the second image portion representing the second portions of the object, based on projections in multiple groups of the plurality of groups and on the reconstructed first image portions.
