mri-reconstruction SKILL.md skillA

mri-reconstruction from kewang0622/mri-research-skill is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add kewang0622/mri-research-skill/mri-reconstruction@v0.14.0

Pins v0.14.0 in mdr.lock. Pin the fingerprint instead.

Read before turning MR data into images or parameter maps: raw k-space (Cartesian, radial, spiral, EPI; twix, ISMRMRD, numpy), GRAPPA/SENSE, coil combination, off-resonance correction, BART or SigPy, and T1, T2/EPG, T2*, water-fat (PDFF), ASL, DCE or QSM maps. Prevents silent errors in encoding sign, acceleration pattern, orientation, noise covariance and floor, water- fat swaps, timing origin and units. Ships tested numpy helpers and a finish check.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# MRFoundry: MRI Reconstruction and Quantitative Maps

Do the work with the tested helpers below instead of re-deriving their maths; open only the row you need.
Hand-written versions of these steps failed silently in evaluation runs.

## Route

| Task | Use (`scripts/`) | Read only if needed |
|---|---|---|
| Undersampled multi-coil Cartesian: R, offset and ACS from the mask, GRAPPA, CG-SENSE, prewhitening, coil combination, SNR units | `mrfoundry_rawrecon.py`: `sampling_pattern`, `grappa_from_mask`, `sense_combine`, `prewhiten` | [raw-data checklist](references/raw-data.md) |
| Non-Cartesian (radial, spiral): exact forward model, NUFFT least squares; off-resonance with a field map | `mrfoundry_reconlib.py`: `offres_least_squares`, `smooth_field` | [raw-data checklist](references/raw-data.md#non-cartesian) |
| Water-fat separation, PDFF, R2* (multi-echo GRE, multi-peak fat) | `fatwater_lib.py`: `fat_offsets_hz`, `fit_fat_water`, `fat_fraction` | [quantitative maps](references/quantitative-maps.md#water-fat) |
| BART or SigPy pipelines; twix, ISMRMRD, `.cfl` files | `bart_recon.sh` | [BART and SigPy](references/bart-sigpy.md) |

How to install

The exact contents, by fingerprint
mdr add kewang0622/mri-research-skill/mri-reconstruction@sha256:314cd5e9fa316764

The line at the top of this page pins the label v0.14.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
