This work does a quantitative evaluation of the effectiveness of a distortion correction method, clinically available at the scanner console, in diffusion MRI of the brain (N=10). After distortion correction, average cross-correlation coefficient between T1 and DWI was significantly increased. Distortion correction reduced average residual distance error to 1.1 mm or less (average 76% reduction) in all of three anatomical landmarks (frontal pole,lateral ventricle, pons). This on-console distortion correction method could help in the clinical applications that requires fast and accurate distortion correction such as deep brain stimulations surgery and cases with high susceptibility such as postoperative cohorts.
