Rotation of a CT image around the RT isocenter, in python

Support
, ,
2

Beginning to see something.
I applied some transformations this way:

vTransform = vtk.vtkTransform()
vTransform.Translate(-0.88, 35.4, 5.65)  # translate by -isocenter
vTransform.Scale(1,1,1)
vTransform.RotateX(30)  # The angle is in degrees
vTransform.Translate(0.88, -35.4, -5.65)
imageNode.ApplyTransform(vTransform)

Now I have to interpret what I am seing, and check if this is what I am looking for…
Any help or comment are still very very welcome…!
Best
