The MRiLab is a numerical MRI simulation package. It has been developed and optimized to simulate MR signal formation, k-space acquisition and MR image reconstruction. MRiLab provides several dedicated toolboxes to analyze RF pulse, design MR sequence, configure multiple transmitting and receiving coils, investigate magnetic field related properties and evaluate real-time imaging technique. The main MRiLab simulation platform combined with those toolboxes can be applied to customize various virtual MR experiments which can serve as a prior stage for prototyping and testing new MR technique and application.

The MRiLab features highly interactive graphical user interface (GUI) for the convenience of fast experiment design and technique prototyping. High simulation accuracy is achieved by simulating discrete spin evolution at small time interval using the Bloch-equation and appropriate tissue model. In order to manipulate large multidimensional spin array, MRiLab employs parallel computing by incorporating latest graphical processing unit (GPU) technique and multi-threading CPU technique. With efficient parallelization, MRiLab can accomplish multidimensional multiple spin species MR simulation at high simulation accuracy and time efficiency, and with low computing hardware cost.

MRiLab is released as a free software. This means that you are free to use and modify this software as your needs, as long as you acknowledge the original author in any future work. If you find MRiLab useful for the publication of any scientific results, including a line in your acknowledgements section referencing to MRiLab is requested.
