AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

The DICOM Series Preflight skill provides a mechanism to inspect DICOM series directories by analyzing headers without decoding pixel data. It generates a structured JSON output containing an inventory of the series, orientation axcodes, potential PHI flags, and a verdict of pass, warn, or fail. This tool is intended for pre-processing validation to ensure data quality before conversion or inference tasks, and it is explicitly not designed for clinical clearance, de-identification, or production ingestion.

What it does

Scans a single DICOM series directory for header-based validation.
Generates a JSON report including inventory, orientation, and findings.
Assigns a preflight verdict of pass, warn, or fail.
Identifies potential PHI flags within the headers.
Provides integration with trusted verifier workflows.

When to use it

Before running inference or conversion on DICOM data.
When you need to verify series orientation and header integrity.
To perform rapid quality checks on medical imaging datasets.
As a gatekeeper in automated medical imaging pipelines.

Advantages

Fast execution due to header-only analysis without pixel decoding.
Standardized output format for downstream automated processing.
Helps identify potential issues early in the data pipeline.
Integrates with existing workflow automation tools.

Usage examples

“Run a preflight check on the DICOM series located in /data/dicom/series_01.”: The agent executes the preflight script on the specified directory and returns a JSON report containing the series inventory, orientation axcodes, and a pass/warn/fail verdict.
“Validate the DICOM series in /data/scan_01 using the trusted preflight verifier.”: The agent runs the preflight script and pipes the output through the trusted verifier to confirm the data meets the required engineering invariants.

Install

Documentation by NVIDIA MedTech Team

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 dicom_dir; outputs are preflight_json.

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 run_script, use run_script("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.	`PATH_TO_DICOM_DIR`

Prerequisites

Runtime requirements: Python packages listed in runtime.side_effects.pip_packages.
NiBabel 5.4 or newer is required so extreme-oblique axes remain labeled consistently across reorientation.
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.
