## Abstract Spiral scanning is a promising MRI method, but one limitation is that off‐resonance effects can cause image blurring. Most current off‐resonance correction methods for spiral imaging require an accurate field map, which is difficult to obtain in many applications. Automatic methods can

## Abstract Field inhomogeneity and susceptibility variations, coupled with a long readout, can result in image blurring in spiral imaging. Many correction methods based on a priori off‐resonance information, such as an acquired field map, have been proposed in the literature. Automatic off‐resonan

## Abstract One primary disadvantage of spiral imaging is blurring artifact due to off‐resonance effects. The conventional frequency segmented off‐resonance correction method that is performed over the entire image is computationally intense due to the large number of fast Fourier transforms (FFTs)

## Abstract Non‐Cartesian imaging provides many advantages in terms of flexibility, functionality, and speed. However, a major drawback to these imaging methods is off‐resonance distortion artifacts. These artifacts manifest as blurring in spiral imaging. Common techniques that remove the off‐reson
