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: , etc.,
• Diffusion models with Laplacian Eigen Functions,
• Magnetic susceptibility,
• Coil sensitivities,
• Documentation.
