OpenKSpace

Pure-Rust library and CLI for Cartesian MRI k-space reconstruction from ISMRMRD .h5 files.

What it does​

OpenKSpace reads ISMRMRD acquisition files, runs a full calibration pipeline, and produces image-domain reconstructions using any of four pluggable strategies. It is designed to be a clean-room reference implementation, easy to read, and fast enough for real clinical-scale acquisitions.

Capabilities​

  • Full AcquisitionHeader parsing with automatic extraction of noise and calibration scans.
  • Automatic detection of 2D multi-slice vs 3D Cartesian encoding.
  • Calibration passes: noise pre-whitening (Kellman & McVeigh 2005), navigator-echo phase correction, readout oversampling removal, partial-Fourier homodyne reconstruction.
  • Reconstruction strategies via the ReconStrategy trait: ifft-rss, grappa, sense (with optional g-factor), cs (FISTA L1-wavelet).
  • SENSE coil-sensitivity maps via Walsh or ESPIRiT.
  • Output: PNG (percentile windowing), NIfTI-1, or both.

Not (yet) supported​

  • Non-Cartesian trajectories.
  • Wave-CAIPI / multi-band SMS.
  • Spiral / radial / EPI distortion correction.

Status​

OpenKSpace is research software. It is not validated for diagnostic use.
