API

This page contains documentation of the public API of MRIReco. In the Julia REPL one can access this documentation by entering the help mode with ? and then writing the function for which the documentation should be shown.

Operators

Operators are implemented as subtypes of AbstractLinearOperator, which is defined in the package LinearOperators.jl. Such operators must provide a function implementing the product and a function implementing the product with the adjoint. Furthermore, the number of rows and columns of the operator must be specified.

Reconstruction

MRIReco.reconstructionMethod
reconstruction(acqData::AcquisitionData, recoParams::Dict)

Performs image reconstruction of an AcquisitionData object. Parameters are specified in a dictionary.

Reconstruction types are specified by the symbol :reco. Valid reconstruction names are:

  • :direct - direct Fourier reconstruction
  • :standard - iterative reconstruction for all contrasts, coils & slices independently
  • :multiEcho - iterative joint reconstruction of all echo images
  • :multiCoil - SENSE-type iterative reconstruction
  • :multiCoilMultiEcho - SENSE-type iterative reconstruction of all echo images
source
MRIReco.reconstructionMethod
reconstruction(acqData::AcquisitionData, recoParams::Dict,filename::String; force=false)

performs the same image reconstrucion as reconstruction(acqData::AcquisitionData, recoParams::Dict) and saves the image in a file with name filename. If force=false, the reconstructed image is loaded from the the file filename if the latter is present.
