About K-Space Reconstruction

[jinfeng2411]

In paper [Joint Deep Model-based MR Image and Coil Sensitivity Reconstruction Network
(Joint-ICNet) for Fast MRI] and [GrappaNet: Combining Parallel Imaging with Deep Learning for Multi-Coil
MRI Reconstruction], they used U-Net to reconstruct parallel MRI in K-space, and achieved a good effect. But in my experiments, using U-net in K-space, the results are terrible. Can anyone give me some advice? I would be very grateful for your help, thanks!

The DIRECT repository has an implementation of Joint-ICNet that you could look into, as well as KIKI-net. The fastmri-reproducible-benchmark repository repository also has an implementation of KIKI-net. I don't now of any open-source implementations of GRAPPANet.
