Read before designing, exporting or simulating an MRI acquisition: pulse sequences, RF and gradient waveforms, k-space trajectories (Cartesian, radial, spiral, EPI), Pulseq/PyPulseq files and Bloch simulation of the export. Prevents silent errors in realized TE/TR/TI and echo spacing, sampling and coverage requirements, spoiling and receive phase, gradient continuity, slice selection, steady state and delivered simulations that differ from a fresh simulation of the file. Ships tested builders…

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: Pulse Sequence and Trajectory Design

Prototype vendor-neutrally with PyPulseq. Treat the build script as a claim and the exported `.seq` as the
evidence: measure the export, simulate the export, reconstruct from the simulation of the export.

## Fast path (sequence -> Bloch simulation -> reconstruction -> report)

1. **Simulator first** (it takes minutes): `pip install pypulseq sigpy matplotlib komamripy`, then start
   `python .agents/skills/pulse-sequence-design/scripts/test_seqlib.py > warmup.log 2>&1 &` (installs Julia +
   KomaMRI; keep logs in the workspace, /tmp may be read-only). If no Julia appears within about 3 minutes (empty
   log, a juliapkg lock wait, an install error), stop it and run
   `sh .agents/skills/pulse-sequence-design/scripts/setup_koma_julia.sh > koma.log 2>&1 &` (Julia 1.10 +
   KomaMRICore in ./koma_julia), then `simulate_with_koma(..., backend='julia')` with the paths it prints. Both
   backends give the same signal. Deliver KomaMRI output only: MRzero, EPG, homemade Bloch code and ideal-signal
   formulas have not matched KomaMRI replays of the same file (scale, sign and timing conventions differ).

How to install

The exact contents, by fingerprint
mdr add kewang0622/mri-research-skill/pulse-sequence-design@sha256:da1651296fd7db74

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.
