MRIsim.jl

MRIsim.jl is a Julia package to simulate Magnetic Resonance Imaging (MRI) acquisitions. The main focus of this package is to simulate general scenarios that could arise in pulse sequence development.

TO-DO:

Phantom and Sequence data-types,
Spin preccesion in gradient-only blocks,
GPU accelaration using CUDA.jl,
RF excitation,
GPU accelaration of RF excitation (under development),
Pulseq IO and auxiliary functions,
Signal "Raw Output" dictionary (ISMRMRD),
MRIReco.jl for the reconstruciton,
Scanner data-type: $B_0,\,B_1,\,G_{\max},\,S_{\max}$ , etc.,
Diffusion models with Laplacian Eigen Functions,
Magnetic susceptibility,
Coil sensitivities,
Documentation.

Installation

To install just do the following:

] add MRIsim

First run

MRIsim.jl comes with a handy GUI that contains a brain phantom with an EPI sequence. To open it use:

SpinLab()

Then, press the button that says "Run simulation!" to do your first simulation :).
