A method and apparatus for MRI retrospective reconstruction determines a period of minimal coronary artery motion within the acquired temporal window with a rotation angle optimized for a K-space four-dimensional (4D) volume by a segmented 4D radial stack-of-stars (SOS) acquisition during a temporal acquisition window (taw). Radial stacks of the image of an object are acquired by performing the radial (SOS) acquisition to determine a plurality of kz plane samples of the object, in which each kz plane is repeatedly determined during a sub-window of the temporal acquisition window. Consecutive volumes of kz centric slices of the image at each temporal sub-window of the temporal acquisition window are generated and summed to fill a 3D k-space volume. The radial (SOS) acquisition of the image is determined utilizing a customized rotation angle θ providing a uniform distribution of k-space spokes of the kz centric slices for each sub-window of the (taw).
