Pipeline for spatial distortion correction in MRI

Published: 26 October 2011 Publication History

Abstract

The recent advances in Magnetic Resonance Imaging gradient, regarding strength and computation speed, led to the development of Echo-Planar Imaging pulse-sequences with faster acquisition times. This kind of sequence is used in functional MRI and diffusion-weighted Magnetic Resonance Imaging and it presents more distortions than slower sequences. This work aims to compare different spatial distortion correction methods for Echo-Planar Imaging sequences with a new proposed pipeline which consists in performing a Field Map correction after a registration process.
