StackofSpiral class

StackofSpiral class is a flexible interface class for non-cartesian gridding. It can handle for 2D spiral/3D stack-of-spirals data. It can easily switch between GPU and CPU computation. For B0 correction with MFI/MTI, StackofSpiralB0 class which is the extension of this class can be used.

Setup

It relies on mainly on three matlab/mex functions and its supporting functions.

  1. nufft_init: NUFFT precomputation
  2. nufft: forward operator
  3. nufft_adj: inverse operator.

CPU functions work out of the box. For GPU, you need to manually copy mex files from gpuNUFFT\gpuNUFFT\@gpuNUFFT\private after compiling the gpuNUFFT package listed below. Alternatevely, you can delete the private folder and add gpuNUFFT to path. The binaries in Spiralreco repo are for windows compiled with cuda 10.1.

  1. mex_gpuNUFFT_adj_atomic_f
  2. mex_gpuNUFFT_forw_atomic_f
  3. mex_gpuNUFFT_forw_f
  4. mex_gpuNUFFT_precomp_f

CPU NUFFT

CPU NUFFT files are from MIRT toolbox of Fessler.
