Extract Wedge Information from DICOM RTPLAN Using Python (Physical & Dynamic Wedges)

Understanding wedge delivery in DICOM RTPLAN is essential for clinical automation, plan checking, and QA workflows — but physical wedges and dynamic wedges are encoded very differently.

This product includes a ready-to-use Python script that extracts wedge information directly from DICOM RTPLAN files, supporting both:

• Physical (standard) wedges

• Dynamic wedges such as Varian EDW and motorized wedge deliveries

The script parses key beam-level and control-point-level structures, allowing you to:

✅ Identify wedge type and angle

✅ Extract wedge orientation and identifiers

✅ Detect dynamic wedge behavior through control points

✅ Build robust automation logic that works across vendors

Included:

• Python wedge extraction script (pydicom-based)

• Clear inline comments for learning and customization

Ideal for:

Medical physicists, automation developers, QA engineers, and anyone working with DICOM RTPLAN data.
