Highlight

• A novel Swin transformer-based model for fast MRI reconstruction was proposed.
• A multi-channel loss with sensitivity maps was proposed for reserving more details.
• Comparison studies were performed to validate the robustness of our SwinMR.
• A pre-trained segmentation network was used to validate the reconstruction quality.

Training and Testing

Use different options (json files) to train different networks.

Calgary Campinas multi-channel dataset (CC)

To train SwinMR (PI) on CC:

python main_train_swinmr.py --opt ./options/SwinMR/train_swinmr_CCpi_G1D30.json

To train SwinMR (nPI) on CC:

python main_train_swinmr.py --opt ./options/SwinMR/train_swinmr_CCnpi_G1D30.json

To test SwinMR (PI) on CC:

python main_test_swinmr.py --opt ./options/SwinMR/test/test_swinmr_CCpi_G1D30.json

To test SwinMR (nPI) on CC:

python main_test_swinmr.py --opt ./options/SwinMR/test/test_swinmr_CCnpi_G1D30.json
