the possibility of changing one of ROIs volumes.

Hi guys.
I am a medical researcher and working on DICOM files in my current project.
I wonder to know is it possible to be able to uniformly extend or shorten one of ROIs in rt-struct DICOM file?
Uniformly extending or shortening PTV(Planning Target Volume) in rt-struct DICOM file and obtaining the overlap volume between this PTV and surrounding Organ at risks (OAR) lead us to calculate OVH (Overlap Volume Histogram) which is a useful feature feeding machine learning models.

Hi @arasheb2001, we currently have no plans for this functionality. What you can do at the moment is extract the ROI data through RT-Utils, run your own custom pipeline for your desired transformation, and update the ROI through RT-Utils. If you would like, you can also make these changes yourself and submit a pull request so that we can include this feature within the library.
