DICOM RT UID Integrity Checker – Validate CT, RTSTRUCT, RTPLAN, RTDOSE Links with Python

🧠 **Worried about mismatched UIDs crashing your TPS?**  

This Python-based tool checks and validates the internal links between the four key DICOM RT files: **CT, RTSTRUCT, RTPLAN, and RTDOSE**. It catches UID mismatches, missing CT slices, and corrupted references *before* they cause problems in your treatment planning system.

✅ **What It Checks:**

- Frame of Reference UID (0020,0052) consistency across all files  

- RTPLAN → RTSTRUCT Referenced Structure Set UID (300C,0060)  

- RTDOSE → RTPLAN Referenced Plan UID (300C,0002)  

- RTSTRUCT → CT contour image references (0008,1155)  

- Per-ROI Frame of Reference UID (3006,0024) inside each structure

💡 **Why Use It?**

• Prevent dose misalignment or failed contour loads  

• Spot errors from anonymization or exported mismatches  

• Save time in QA, automation, or clinical scripting  

• Easy to run from terminal — just point to your DICOM folder

📦 **What’s Included:**

- Python script (`dicom_rt_link_checker.py`)  

- Sample instructions (in-code comments)  

- Lightweight, no installation required beyond `pydicom`

📌 **Perfect For:**

- Medical physicists  

- TPS QA developers  

- Radiation therapy automation projects  

🔧 Built with ❤️ by a practicing medical physicist + DICOM scripting expert.
