DICOM-Based Dose Grid Coverage Check – Ensure Accurate DVH Metrics

Verify Dose Grid Coverage in Seconds — No TPS Needed

This Python tool automatically checks whether any contour lies outside the dose grid using only DICOM RTSTRUCT and RTDOSE files. It’s a fast, TPS-independent way to catch critical coverage issues before final plan approval.

🔍 Key Features:

✅ Loads RTSTRUCT and RTDOSE DICOM files directly

✅ Extracts structure contours and dose grid bounds

✅ Detects structures partially or fully outside the dose grid

✅ Provides clear warnings and summary output

✅ Compatible with any treatment planning system export

💬 Why It Matters:

When parts of a structure extend beyond the dose grid, DVH values become inaccurate, potentially misrepresenting dose coverage and affecting clinical decisions. This check ensures your reported plan metrics truly reflect the delivered dose.

⚙️ Requirements:

• pydicom, numpy only

🧠 Ideal For:

Medical physicists, researchers, and QA teams who need a TPS-independent quality check for DICOM dose data.
