SBRT Plan Metrics Automation: D2cm, R50, NT105, CI & PTV Volume (DICOM)

📊 Automate SBRT Plan Evaluation in Seconds

This DICOM-based Python script automates extraction and evaluation of key SBRT metrics — enabling fast, consistent, and TPS-independent plan analysis across large datasets.

🔍 Script Features:

✅ Automatic PTV volume calculation

✅ R50: Ratio of 50% isodose volume to PTV

✅ D2cm: Maximum dose 2 cm away from PTV (0.035 cc)

✅ NT105: Volume outside PTV receiving > 105% dose

✅ Conformality Index (CI)

✅ Violation Classification: None / Minor / Major (RTOG 0813 thresholds)

✅ CSV Export + Instant On-Screen Summary

Whether analyzing single cases or entire cohorts, this tool streamlines SBRT plan review — making evaluation faster, reproducible, and fully documented.
