Python Script: Extract DVH Statistics from RTDOSE and RTSTRUCT DICOM Files

Easily extract Dose-Volume Histogram (DVH) statistics from RTDOSE and RTSTRUCT DICOM files using this simple, ready-to-use Python script!

This script offers a straightforward method to:

✅ Load RTDOSE and RTSTRUCT DICOM files

✅ Map structure contours to the dose grid

✅ Extract dose values inside structures

✅ Build DVH data for quick analysis

✅ Save DVH results as a CSV file

Key Features:

• Simple voxel mapping (nearest neighbor method)
• No external libraries beyond basic Python and pydicom
• Perfect for research, automation, and personal learning projects
• Fast setup and easy to customize for your needs

Important Notes:

• This script uses a basic voxel mapping approach without advanced interpolation (e.g., no trilinear interpolation).
• Point-type structures are not excluded automatically.
• Suitable for research and automation projects, but may require refinement for clinical precision use.

What's Included:

• Python script (.py) file
• Example usage instructions

Ideal for:

• Medical physics researchers
• Medical imaging enthusiasts
• Developers working with DICOM RT data
• Anyone interested in automating DVH extraction!
