KomaMRI.jl is a Julia package for highly efficient ⚡ MRI simulations. KomaMRI was built from the ground up to be: easy to use, extensible, cross-platform, and powered by open-source community standards.

- (7 Dec 2023) Koma was present in MRI Together 😼. The talk is available here. Also, I uploaded the promised educational example.
- (17 Nov 2023) Pretty excited of being part of ISMRM Pulseq's virtual meeting. The slides available here.
- (27 Jul 2023) I gave a talk at MIT 😄 for JuliaCon 2023! A video of the presentation can be seen here.
- (29 Jun 2023) KomaMRI.jl's paper was chosen as a July editor's pick in MRM 🥳!
- (6 Mar 2023) Paper published in MRM 😃!
- (8 Dec 2022) KomaMRI v0.7: improved performance (5x faster), type stability, extensibility, and more!
- (17 May 2022) ISMRM 2022 digital poster presented in London, UK. Recording here!. Name change MRIsim.jl -> KomaMRI.jl.
- (Aug 2020) Prehistoric version of Koma, MRIsim, presented as an ISMRM 2020 digital poster (virtual conference).
☰ Roadmap
v1.0:
- Phantom and Sequence data types,
- Spin precession in gradient-only blocks (simulation optimization),
- GPU acceleration using CUDA.jl,
- RF excitation,
- GPU accelaration of RF excitation,
- Scanner data-type: , etc.,
- Pulseq IO,
- Signal "Raw Output" dictionary (ISMRMRD),
- MRIReco.jl for the reconstruciton,
- Documentation,
- Auxiliary Pulseq functions,
- Coil sensitivities,
- Cardiac phantoms and triggers.
- decay,
Next:
- Diffusion models with Laplacian Eigen Functions,
- Magnetic susceptibility,
- Use PackageCompiler.jl to build a ditributable core or app.
To install, just type ] add KomaMRI
in the Julia REPL or copy-paste the following into the Julia REPL:
pkg> add KomaMRI
For more information about installation instructions, refer to the section Getting Started of the documentation.
KomaMRI.jl features a convenient GUI with predefined simulation inputs (i.e. Sequence
, Phantom
, and Scanner
). To launch the GUI, use the following command:
using KomaMRI
KomaUI()
Press the button that says "Simulate!" to do your first simulation :). Then, a notification will emerge telling you that the simulation was successful. In this notification, you can either select to (1) see the Raw Data or (2) to proceed with the reconstruction.
KomaMRI exists thanks to all our contributors:

All parallel backends are tested on Linux (besides Apple silicon) using the latest stable release, Julia 1 (stable), and Julia 1.9 (compat).
Single-threaded compatibility is tested in all major operating systems (OS).
