Claim 4:
5. A non-transitory computer readable medium storing instructions that, when executed by at least one computer, cause the at least one computer to:
specify a set of radial k-space spokes to cover a spherical k-space volume, such that spokes of the set of radial k-space spokes are between a k-space origin and end points distributed on a surface of the spherical k-space volume;
select subsets of a predetermined number of spokes from the specified set of radial k-space spokes so that concatenation of the spokes contained in each of the subsets forms a closed trajectory in k-space, wherein selecting the subsets is based on a cost function favouring (i) minimizing a maximum angle between subsequently acquired spokes within the same_subset, (ii) maximizing a uniformity of the distribution of the end points of the spokes on the surface of the spherical k-space volume, while ensuring that the concatenation of the spokes of each of the subsets forms the closed trajectory in k-space;
generate a zero echo time imaging sequence, wherein each of the subsets is acquired as a sequence of gradient echo signals;
reconstruct an MR image from the acquired spokes; and
cause the reconstructed MR image to be displayed on a video monitor.
