Artifact Correction in Echo Planar Imaging: CIS

Susceptibility Artifact Correction in Echo Planar Imaging

Left column: Clearly visible artifacts in so called blip-up and blip-down images. Upper right: Corrected blip-down image. Bottom right: Corresponding T1-weighted MR.

The aim of this project is to test a new approach for susceptibility artifact correction in echo planar imaging (EPI). Modeling the EPI-typical deformations along the phase encoding gradient together with mass preserving registration techniques is in focus of this project.
