Free-Breathing MR Fingerprinting

Free-breathing MR Fingerprinting acquisitions of the abdomen. One dataset is acquired with the normal ordering, the other with the motion-robust ordering, as described in the article "Free-Breathing Abdominal T1 Mapping using an Optimized MR Fingerprinting Sequence". The data acquired with the normal ordering shows artifacts caused by respiratory motion, while these artifacts are reduced by using the proposed motion-robust ordering of the acquired k-space.

Because of the size of the datasets, only a single dataset is uploaded. This dataset was acquired at a resolution of 1.0 mm x 1.0 mm x 3.0 mm, as shown in Figure 9 in the paper. For the complete dataset, please contact the authors ([e-mail]).

背景概述

该数据集为自由呼吸腹部MR指纹采集数据，包含正常顺序和运动鲁棒顺序两种采集方式，旨在通过优化序列减少呼吸运动伪影。由于数据体积较大，仅上传了单个分辨率示例数据集，完整数据需联系作者获取。
