I am trying to define the minimum and maximum values of the slides in the volume widget (see screenshot - it is the widgets circled in red).
For clarity this is not the min-max of the WindowLevel.
Which widget do these elements belong to and how what is the most appropriate way to read/write them?
Once you have a qMRMLWindowLevelWidget object, you can use the
volume_node = SampleData.SampleDataLogic().downloadMRHead()
window_level_widget = slicer.qMRMLWindowLevelWidget() # creates a new window/level widget object
You can also see discussion linked below about why you might use Window/Level values that are outside of the scalar range and why the values of -600 to 600 are chosen in the image you show.
Thanks. That works!
The other part I am having trouble working out is how to identify and access the existing WindowLevelWidget that is associated with PET Scalar volume.
For reference below is how I worked out to access the existing window level widget.
Very interested to hear if there a better / cleaner approach. thanks.
ui = slicer.util.getModuleWidget("Volumes")
ui_children = slicer.util.childWidgetVariables(ui)
windowLevelWidget = ui_children.MRMLWindowLevelWidget
