Cardiac Cine Data

该数据集是通过使用一个配备有32元素心脏线圈阵列的3T全身MRI扫描仪获取的心脏电影数据。采用前瞻性心脏门控的bSSFP序列进行数据捕捉。此外，作为基准真值，使用了完全采样的k空间数据；而回顾性欠采样则采用了2D黄金角度径向采集方案。该数据集包含了23帧，时间分辨率为43.2毫秒，任务是对动态MRI进行重建。

This dataset consists of cardiac cine MRI data acquired using a 3T whole-body MRI scanner equipped with a 32-element cardiac coil array. Data acquisition was performed with a balanced steady-state free precession (bSSFP) sequence employing prospective cardiac gating. Furthermore, fully sampled k-space data were utilized as the ground truth, while retrospectively undersampled data were acquired via a 2D golden-angle radial acquisition scheme. This dataset contains 23 frames with a temporal resolution of 43.2 ms, and the associated task is dynamic MRI reconstruction.
