Abstract:
A method for three-dimensional MR imaging of a region within a subject, wherein said region is disposed to experience cyclical motion, said method comprising the steps of:detecting commencement of each of a succession of said motion cycles;acquiring a set of MR views of said region during each motion cycle of said succession, wherein each of said views is at a known radial distance from the center of a two-dimensional k-space, and wherein each of said sets includes a lowest frequency view located proximate to said k-space center[; ]and a higher frequency view, the higher frequency view of a set being located farther from said k-space center than the lowest frequency view thereof;acquiring each of said lowest frequency views at a specified time after commencement of its corresponding motion cycle, said specified time being the same for all of said lowest frequency view acquisitions; andacquiring the highest frequency view of a set prior to acquiring the lowest frequency view thereof.
