Beam Isocenter Checker – Verify Treatment & Setup Beam Geometry from DICOM RT Plan

Ensure precise and consistent beam geometry before treatment with this Python-based Beam Isocenter Checker.

This script automatically reads your RT Plan DICOM file and:

• Checks all beams share the same isocenter (critical for plan quality assurance)
• Distinguishes setup beams vs. treatment beams
• Flags beam geometry inconsistencies before they cause downstream issues

Key Features:

• Fully automated – just point it to your RT Plan file
• Supports standard DICOM-compliant RT Plans from major TPS systems
• Output includes a clear pass/fail report for easy documentation
• Built with pydicom for easy customization to your workflow

Perfect for:

• Medical physicists performing pre-treatment plan checks
• QA teams looking to streamline beam geometry verification
• Researchers working with treatment plan datasets

Format: Python script (.py)
