PROBLEM TO BE SOLVED: To provide a method and apparatus for generating an optimally registered working set of two-dimensional CT images in a gated CT system. SOLUTION: The method (140) includes, where an acquisition period is divided into sequential acquisition phases, obtaining CT image data for separate phase ranges during each acquisition phase (142), generating phase image sets including 2D images for each phase range (152), and selecting one phase range image set corresponding to each acquisition phase (158, 160, 162) to generate a working image set where the selected phase range image sets are optimally aligned.
