Abstract:
A method of shifting of motion based artifacts in images produced with a magnetic resonance imaging system, comprising:selecting a segment of a plurality of segments comprising a selected number of k-space lines of k-space data for a temporal series; selecting a time interval from a plurality of time intervals for acquisition; acquiring N sets of k-space lines comprising every Nth k-space line of said segment for successive 1/N portions of said time interval and repeating said acquiring for successive sets of said N sets of k-space lines and wherein N is an integer greater than one; repeating said acquiring for each time interval of said plurality of time intervals and for each segment of said plurality of segments; and wherein said k-space data are reconstructed employing a time weighted average based upon respective time of said acquiring k-space lines from said k-space data acquired employing said magnetic resonance imaging system.
