Claim Text:
1. A method for providing an image of a subject in a magnetic resonance imaging MRI system, comprising: defining a plurality of Cartesian points on a k dividing the plurality of Cartesian points into a first group (Group A) and a second group (Group B), wherein all of the Cartesian points in the first group have a k dividing the second group into N subgroups, wherein N is a whole number greater than or equal to two, wherein the subgroups have an incoherent point spread function; applying an inversion recovery (IR) radio frequency to the subject such that a net longitudinal magnetization in the subject is substantially inverted and begins to relax back to equilibrium; acquiring k-space data for the first group of Cartesian points for M different time periods, wherein k-space data is acquired for only one sub-group for each time period of the M different time periods, and wherein k-space data is acquired for each subgroup sequentially and cyclically for the M different time periods; for each time period i of the M different time periods, using acquired k-space data for the first group of Cartesian points at time period i and k-space data from N consecutive subgroups of Cartesian points where one of the N consecutive subgroups is the subgroup that is acquired during time period i to create image data of the subject for first time period i.
