Python Script: Extract Beam-Level Dose Point Data from DICOM RTPLAN

This product provides a ready-to-use Python script for extracting beam-level dose point information directly from DICOM RTPLAN files.

The script parses the Fraction Group Sequence and Referenced Beam Sequence to retrieve beam-specific dose and geometry parameters commonly used in QA, automation, and secondary-check workflows.

It is designed for medical physicists, dosimetrists, and developers who work directly with DICOM data and need a reliable, transparent way to access RTPLAN beam-level dose point fields.

✅ Extracted DICOM Tags (Per Beam)

The script extracts the following standard DICOM RTPLAN attributes:

• Beam Dose (300A,0084)
• Beam Meterset (300A,0086)
• Beam Dose Point Depth (300A,0088)
• Beam Dose Point Equivalent Depth (300A,0089)
• Beam Dose Point SSD (300A,008A)

All values are extracted per beam, preserving the beam-level structure defined in the RTPLAN.

🧠 Key Features

• Beam-specific parsing using the Referenced Beam Sequence
• Clear separation of data by beam number
• Safe handling of missing or optional tags
• Clean, readable output suitable for:
• QA checks
• Secondary dose verification
• Automation pipelines
• Debugging RTPLAN exports
• No TPS-specific assumptions (vendor-neutral DICOM)

👩‍⚕️ Intended Users

• Medical Physicists
• Dosimetrists
• QA / Automation Developers
• Anyone working with DICOM RTPLAN files
