DICOM Series Preflight

Purpose

  • Used for header-only preflight of one DICOM series folder before conversion or inference. Not for de-identification or clinical clearance.
  • Use the wrapper exactly as documented; do not replace the upstream entrypoint with a handwritten implementation.
  • Manifest I/O: inputs are dicomdir; outputs are preflightjson.

Instructions

  • Read skill_manifest.yaml before changing arguments, side effects, or validation gates.
  • Run scripts/preflight_series.py through the documented command below; keep outputs under a caller-provided run directory.
  • If a host agent exposes runscript, use runscript("scripts/preflight_series.py", args=[...]); otherwise run the Bash/Python command shown below.
  • Check the emitted JSON and paired verifier guidance before treating the run as evidence.

Available Scripts

Script Purpose Arguments
scripts/preflight_series.py Primary entrypoint declared by skill_manifest.yaml. PATHTODICOM_DIR

Prerequisites

  • Runtime requirements: Python packages listed in runtime.sideeffects.pippackages.
  • Run commands from the repository root unless an existing section below says otherwise.

Limitations

  • Header-only; does not decode pixel data or detect burnt-in PHI.
  • Canonical orientation gate assumes LPS-derived CT axcodes L,P,S.
  • Compressed transfer syntax and multi-frame instances are warned, not decoded.
  • Single-directory scan; does not reconcile multiple studies in one tree.
  • Not for clinical deployment, regulatory de-identification, autonomous diagnosis, production ingestion without a vetted converter.

Troubleshooting

Error Cause Fix
Missing dependency or import error Runtime package drift from skill_manifest.yaml. Install the packages declared in the manifest or use the documented setup command.
Empty or schema-invalid output Wrong input path, unsupported modality, or upstream failure. Re-run with a known fixture and inspect the wrapper JSON plus stderr.
Validation gate failure Output violated a declared engineering invariant. Keep the failed evidence pack and use the gate message to repair inputs or wrapper code.

Scans a DICOM directory (one series per folder) without decoding pixels. Emits JSON with inventory, orientation axcodes, PHI flags, findings, and a preflight.verdict of pass, warn, or fail.
