1. A computer programmed to generate computed tomographic (CT) images from scan data acquired during different biological cycles, said computer programmed to: receive scan data acquired during a gated acquisition window of each of a plurality of biological cycles; generate blended redundant projection data by combining the scan data using view dependent blending, z-axis dependent blending, and cardiac segment view weighting, wherein a segment weight is based on data acquired in an angular range at least equal to a halfscan; construct a first image from a first of the plurality of biological cycles; construct a second image from a second of the plurality of biological cycles, wherein the second image comprises a region of overlap with the first image to define a transition region; and construct a final image comprising the first image and the second image, wherein the transition region is defined using adaptive blending of the blended redundant projection data constructed from the first image and the second image using weighting factors that vary from pixel to pixel.
