Free-breathing supine breast MRI k-space and respiratory data

This data is used in the demo of the GRICS-torch code which performs motion-corrected MRI reconstruction. This data contains k-space and respiratory bellow data per k-space line for one slice of free-breathing supine breast MRI. This is a small subset of the data used for the publication Isaieva et al. MRM 2023 where its acquisition protocol is described in details.本数据集用于搭载运动校正磁共振成像（Magnetic Resonance Imaging, MRI）重建功能的GRICS-torch代码的演示程序。 本数据集包含单一层面自由呼吸仰卧位乳腺MRI的每条k空间（k-space）线对应的k空间数据与呼吸带信号数据。 本数据集为伊萨耶娃等人（Isaieva et al.）2023年发表于《磁共振医学（Magnetic Resonance in Medicine, MRM）》的论文所用数据的小子集，该论文详细阐述了本数据集的采集协议。
