Near term goals

[fzimmermann89]

This is for me as a notepad for stuff that I think we should consider before publication:

Missing stuff

Examples:

• qualitative superresolution image reconstruction
• motion corrected t1 mapping with given motion fields?
• Simple shallow var net with differentiable solver
• TV regularized reconstruction with stronger regularization outside of the body (demonstrating spatially varying regularization strength)

functionals

• scaled functional #386
• stacked functional #308

Operators

• Differentiable Optimization Operators: Differentiable Optimization and Differentiable solver.
• nufft op (torchkbnufftop, finufftop?) #300
• nufft autograd wrapper, allowing for gradient wrt ktraj and compatible with torch.func.

algorithms

• pdhg

Indexing #382 #298 #243

• indexing for subsetting

• rearrange

  Writing data #401

• exporting to ismrmrd
• exporting to dicom

Reading in data without valid header (nice to have, usefuull but not content of paper)

• moving the sorting logic into a separate function in Kdata.from_ismsmrd to call it afterwards.
• example of fixing the header inside mrpro. I.e. how to read In old piulseq data without idx etc
