This are a collection of script to perform benchmarking of MRI-NUFFT operations.

They rely on the hydra configuration package and hydra-callback for measuring statistics. (see requirements.txt)

To fully reproduce the benchmarks 4 steps are necessary:

0. Get a Cartesian Reference image file, name cpx_cartesian.npy
1. Generates the trajectory files python -m trajectory.py
2. Run the benchmarks. Currently are available:

• The Performance benchmark, checking the CPU/GPU usage and memory footprint for the different backend and configuration perf folder.
• The Quality benchmark that check how the pair trajectory/backend performs for the reconstruction. in qual folder

3. Generate some analysis figures using perf_analysis.py
