ParXRec.jl

Julia package for loading Philips' PAR/REC and XML/REC files.

Installation

ParXRec requires Julia v1.0 or later.

julia> ]add ParXRec

Usage

Load PAR/XML header and REC data:

using ParXRec

rec = ParXRec.load("file.{PAR, XML, REC}")
hdr = rec.hdr
data = rec.data

Load PAR/XML header only:

rec = ParXRec.load("file.{PAR, XML, REC}", load_data = false)
hdr = rec.hdr

Extract data dimensions, voxel size, and echo times from header:

sz  = datadims(hdr)
vsz = voxelsize(hdr)
TEs = echotimes(hdr)

Notes

• Supports PAR versions 3, 4, 4.1, 4.2.

• REC data is sorted and loaded into a single array. The dimensions are:

  • slices
  • echoes
  • dynamics
  • cardiac phases
  • diffusion b values
  • gradient orientations
  • label types
  • image types
  • sequences

  Singleton dimensions (except for slices) are removed.
