Extract DICOM Approval Status from RTPLAN, RTSTRUCT, and RTDOSE Using Python

🔍 Extract approval information directly from radiation therapy DICOM files using Python.

This script allows you to read and display DICOM Approval Module information from:

📄 RT Plan (RTPLAN)

🧩 RT Structure Set (RTSTRUCT)

💊 RT Dose (RTDOSE)

✅ Extracted DICOM Tags

The script extracts important approval-related tags including:

✔ Approval Status (300E,0002)

📅 Review Date (300E,0004)

⏰ Review Time (300E,0005)

👤 Reviewer Name (300E,0008)

The tool automatically detects the RT object type and safely handles cases where approval tags are missing, since the Approval Module is optional depending on vendor export behavior and TPS configuration.
