Hi, am interested. Please let me know the next steps.
Hello @sriram-1, that would be fantastic! I think the first thing would be to read the paper and understand the mathematics of how the single-coil data was simulated. Then you could create a function with a signature like
def simulate_singlecoil_from_multicoil(kspace: Tensor) -> Tensor:
# write function here
that would return the single-coil k-space based on the paper.
Create a new folder under fastmri_examples
called singlecoil_simulation
and include a Jupyter notebook using your function and plot the reconstruction. Compare the reconstruction from single-coil to the reconstruction from multi-coil. The single-coil should be noisier.
Once you have all this you can open a pull request and I'll review it. Once everything looks good we can merge it into the repo.
This issue would add code for simulating the single-coil data from multi-coil data described in the following paper:
