Implementation and Application of PSF-Based EPI Distortion Correction to High Field Animal Imaging
Comparison of results from EPI distortion correction using accelerated PSF data acquisition with reduced FOV. Image (a) shows a T2w SE-EPI after distortion correction using a PSM from full PSF data acquisition. For comparison, (b) and (c) show results from the correction process using PSF data with 2x and 4x acceleration. No difference in image quality can be seen. The difference images between images (a)-(b) and (a)–(c) are given in the lower row as (d) and (e), respectively.
