We have modified Xrecon to include a matlab pipe, allowing for remote reconstructions on another (beefier) computer. This is particularly useful for compressed sensing and parallel imaging, as it allows the use of an off-host GPU.

This is implemented via:

  • a patched version of Xrecon, nominally located in /vnmr/imaging/src,
  • a pipe script that contains ssh details to the remote host,
  • and code that runs on the remote (GPU'd up, matlab-wielding) host.

Naturally, wrappers can easily be written to gadgetron or BART as appropriate.

To use this code in VnmrJ sequences, set apptype='immatlab'.
