MatMRI: A GPU enabled package for model based MRI image reconstruction

Baron, Corey A; Dubovan, Paul I

MatMRI is a package for MRI image reconstruction using only core or toolbox MATLAB® functions (i.e., no mex files or pre-compiled binaries). This philosophy is used to enable easy integration with built-in MATLAB® GPU functionality, and to minimize dependencies. It currently supports:

  • non-Cartesian regridding
  • iterative SENSE (Cartesian or non-Cartesian)
  • iterative SENSE for higher order models that may include:
    • an off-resonance map
    • time varying spherical harmonics of phase accrual
  • compressed sensing for higher order models
  • spherical harmonic estimation using raw field probe data
