Claim:
1. A method for controlling a magnetic resonance (MR) imaging system to provide retrospective reconstruction of an object image of a four-dimensional (4D) volume by an optimized rotation angle, the method comprising: generating a magnetic field around an object by a main magnet and a gradient magnetic coil; receiving a signal from the object by a radio frequency coil; acquiring a temporal acquisition window based on an associated motion period of the object image, acquiring a plurality of image slices of the object, in which each k in response to a request, selecting a temporal acquisition sub-window for retrospective processing of the image slices to determine a period of minimal objection motion within the acquired temporal window; wherein the rotation angle is optimized for a segmented 4D radial stack-of-stars acquisition during the temporal acquisition window by: displaying an image based at least in part on displaying the reconstructed object image based at least in part on the period of minimal objection motion; wherein the radial stack-of-stars (SOS) acquisition of the image is determined utilizing a customized rotation angle θ to provide a uniform distribution of k-space spokes of the k
