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.

MRI空间畸变校正的管道

磁共振成像梯度在强度和计算速度方面的最新进展，导致回波平面成像脉冲序列的发展，具有更快的采集时间。这种序列用于功能磁共振成像和弥散加权磁共振成像，它比慢序列呈现更多的畸变。这项工作旨在比较不同的空间畸变校正方法回声平面成像序列与新提出的管道，包括执行一个场图校正后配准过程。
