Open source resources

Below are concise overviews of notable open‑source MRI projects with back‑links.

Shimming Toolbox

Open‑source tools for B0 shimming workflows: importing field maps, masking, shim optimization (e.g., spherical harmonic or multi‑coil), and evaluation pipelines for research and education.

Website: Shimming Toolbox (stable)

PulSeq

Vendor‑neutral, text‑based description of MRI pulse sequences. Lets you define RF/gradients/events once and run them on supported executors across vendors or research consoles.

Website: PulSeq

MaRCoS

Low‑cost/open MRI control system centered on the Red Pitaya SDRlab 122‑16. Provides server/FPGA/client stack and supports executing PulSeq definitions; aimed at low‑field research and teaching.

GitHub: MaRCoS

Gadgetron

Streaming MRI reconstruction framework (C++). Uses ISMRMRD, with modular “gadgets” pipelines for online/real‑time recon; supports integration with custom algorithms and optional acceleration.

BART (Berkeley Advanced Reconstruction Toolbox)

Command‑line MRI reconstruction toolbox. Implements parallel imaging and compressed‑sensing methods (e.g., NUFFT, ESPIRiT calibration), plus rich k‑space/image processing utilities for reproducible workflows.
