Data:

The data used for the image super-resolution task comes from the fastMRI dataset and M4Raw.

The multi-contrast MR images csv file is released in dataset fold. fastMRI csv file comes from MINet.

Within each task folder, the following structure is expected:

    data0/fastmri_knee
    ├── singlecoil_train
    │   ├── xxx.h5
    │   ├── ...
    ├── singlecoil_val
    │   ├── xxx.h5
    │   ├── ...

    data0/M4RawV1.1
    ├── multicoil_train
    │   ├── xxx.h5
    │   ├── ...
    ├── multicoil_val
    │   ├── xxx.h5
    │   ├── ...
