A simulation package named MRiLab is introduced here for performing efficient and flexible 3D numerical MRI simulation on simple PC. MRiLab features user-friendly interface and optimized programming-free modules that well suits for MR pulse sequence design and image reconstruction technique development. Associated tools are also provided for analyzing multiple spin evolution, MR signal and k-space formation, local SAR distribution, etc. With the simulation acceleration accompanied by GPU and multi-threaded CPU, MRiLab has proven to be a fast and effective parallel simulation framework with minimum computation hardware requirements.
