MRRT Nufft

[paquiteau]

Hi, while looking for other stuff, we found an another NUFFT backend with @chaithyagr:

https://github.com/mritools/mrrt.nufft

Its a interesting one: fully written with a Python Stack (Cython / numba /Cupy) and is basically a port of Fessler's NUFFT from MATLAB. It has:

• both support for CPU and GPU
• single or double precision.
• Multi coil support (but without SENSE reconstruction)
