Is Beam extended box checked ?

[yvsblanc]

I would make a script where I will check some characteristics of my treatment plans and for some beams i would like to know Where I could find if, for a 180° beam, the extended box is checked or not. I didn't find any property in the Beam class to do this. If someone know how to do this it would help me. Thanks

Maybe you should consider to use Varian's DICOM API to explore DICOM Tags related to Beam inside your DICOM Plan.

In Eclipse 16.x, the Beam object has two properties:

• Beam.IsGantryExtended Checks if the gantry rotation is extended. For arc beams, checks if the gantry rotation is extended at the start angle.
• Beam.IsGantryExtendedAtStopAngle Checks if the gantry rotation is extended at the stop angle of an arc beam.

Thank you for your help I don't have this Beam properties in my Eclipse 15 and I don't see how to explore the DICOM tags to find other things than the beam properties availables.
