RTSTRUCT QA Toolkit: Detect Contour Errors & Missing Slices in Python

🔍 RTSTRUCT QA Toolkit (Python)

In radiation therapy workflows, RTSTRUCT files often appear correct at first glance —

but subtle contour errors can still exist and impact downstream processes.

This toolkit helps you automatically detect two common but critical issues:

✔️ Disconnected contour islands

✔️ Missing contour slices in the Z-direction

💡 Why this matters

Manual contour review is time-consuming and not always reliable.

Small geometry issues can be easily missed but may affect:

• Dose evaluation
• Plan QA workflows
• Data integrity during DICOM transfer
• Research and automation pipelines

This tool provides a fast, automated way to validate RTSTRUCT integrity.

🧑‍⚕️ Who this is for

• Medical physicists
• Dosimetrists
• Researchers working with DICOM RT data
• Anyone building automation pipelines in radiation oncology

🚀 What you can do with it

• Integrate into your plan check workflow
• Use as a starting point for DICOM-based QA systems
• Demonstrate contour QA concepts (great for teaching & presentations)
• Build toward TPS-agnostic plan check tools

👉 Start automating your RTSTRUCT QA today and catch issues before they propagate.
