A stack of spirals trajectory is one of the commonly used non-Cartesian 3D trajectories, and it can increase the scan efficiency by an order of magnitude compared to standard 3D methods. The main factor limiting the reliability of spiral imaging is image blurring caused by off-resonance effects. We propose a method for performing 3D off-resonance correction for a stack of spirals trajectory by performing 2D off-resonance correction slice by slice in 3D. This method simplifies the calculations and increases the ffectiveness of the image deblurring.
