EQD2 Dose Converter (Python Script) — Convert RTDOSE to EQD2 Directly from DICOM

Convert RTDOSE → EQD2 in seconds with this Python-based DICOM tool.

This script provides a fully DICOM-native, TPS-independent workflow for computing EQD2 dose distributions directly from RTDOSE files.

Whether you're validating radiobiological models, building automation tools, or performing independent dose checks, this tool generates a clean and reliable EQD2 RTDOSE file that can be imported into any DICOM-compliant system.

✨ Key Features

• ✔️ Full DICOM-native implementation (pydicom — no TPS required)
• ✔️ Converts RTDOSE → EQD2 voxel-by-voxel using the linear-quadratic model
• ✔️ Automatically calculates a safe DoseGridScaling for export
• ✔️ Preserves FrameOfReferenceUID for correct CT/dose alignment
• ✔️ Generates new DICOM UIDs for clean import into any system
• ✔️ Removes ReferencedRTPlanSequence so the exported file is treated as an evaluation dose
• ✔️ Produces a new RTDOSE file compatible with all DICOM-compliant TPS, PACS, and viewers
• ✔️ Clean, well-commented Python code — easy to modify for research or workflow development

🎯 Perfect For

• Medical physicists
• DICOM developers
• Researchers studying radiobiology and EQD2
• Automation engineers
• Anyone who needs biological dose visualization outside the TPS
