Variable splitting network for accelerated parallel MRI reconstruction

l1-spirit

Can you provide code on how you implemented the l1-spirit method? I am trying to use python-based bart tool to implement the method, but the results are not coming in range. Also, obtaining sensitivity map from the given k-space is not equal to the provided sensitivity map. Is there any reason behind this ?

how can i fix it？thanks！

GLOBUS-Dataset download probelm

Hello, I was replicating your code recently, but there was a problem in downloading the data set. I could not download it directly from the data set link you gave me in GLOBUS. After many attempts, I was reminded that the download failed. So, do you have any other downloading methods? Thank you!
