How to create mask for tandem and ovoid?

[Suman-c21]

We have tandem and ovoid in the brachytherapy. I have problem in creating a mask for tandem and ovoid using the rtutils. This package successfully load and create an existing RT structure contour as mask for OARs like Bladder, rectum, sigmoid and hrctv. But it gives and error for creating mask for tandem and ovoid. Could anyone help me in figuring out?

Thank you

What kind of dicom files are your tandem and ovoids found in? What error is it giving you?

The error is
AttributeError: 'Dataset' object has no attribute 'ContourImageSequence'

Are you loading an existing RTStruct or are you creating a new one?

Is your RT Struct file properly constructed? Each ROI should have an associated contour sequence that has a contour image sequence with contour data per slice
