Correction for Geometric Distortion in Echo Planar Images

Description

We have developed a variational image-based approach to correct the susceptibility artifacts in the alignment of diffusion weighted and structural MRI.The correction is formulated as an optimization of a penalty that captures the intensity difference between the jacobian corrected EPI baseline images and a corresponding T2-weighted structural image.

Coronal slice from a fieldmap corrected EPI (left). The same slice using proposed correction method (right).
