(a) Flexible image reconstruction at an arbitrary temporal resolution using golden-angle radial sampling. Different temporal resolutions can be achieved by grouping different numbers of consecutive spokes at the desired temporal positions. (b) Images reconstructed at different temporal resolutions using conventional gridding (NUFFT) and the proposed iGRASP method. Note that the spatial features of the breast parenchyma are well preserved for all images reconstructed using iGRASP.
