Rapid Concomitant Field Correction for 2D Spiral Imaging

Ajit Devaraj¹, Payal Bhavsar¹, James G. Pipe¹

Concomitant fields are a source of artifact for non-axial spiral images. The resulting artifacts are similar to Bo in-homogeneity blurring, hence challenging to account for. This work presents a rapid approach based on separable de-blur kernels. The efficacy of the proposed approach is demonstrated on both simulated and phantom sagittal images.
