I’m currently developing a Python scripted module. Shortly after the module starts running, it pauses to allow the user to select a region of interest from an image by adjusting a vtkMRMLAnnotationROINode. I would like to add a dropdown menu that appears only during this paused for ROI selection stage so that the user can choose which image they want to display during ROI selection. I know how to load an image from a numpy array into a vtkMRMLScalarVolumeNode and then display that node. What I don’t know is:
-How to choose your own names for each vtkMRMLScalarVolumeNode
-Python code to create a dropdown menu and how to make each selection from dropdown menu prompt display of a different image in Slicer window
Any help with syntax for this would be greatly appreciated.
