Hello, I am trying to annotate my CTP data using Markups Plane. There are a total of 158 slices in my CT data. I want to create Markup Plane in only 1 slice and copy the markup for 3 slices above and 3 slices below of that slice. Is there a way to do that automatically? In that way, I don’t have to draw markup plane 7 times for 7 slices. I can draw just one markup plane and it will be automatically copied to 6 other slices (3 top and 3 below).
I know that I can use 3D ROI to cover multiple slices together. But I need the 2D markup plane for this project.
Please let me know if there is such option in slicer. Also, can I write a code in Python Interactor window to do this?
If you really want to have 7 duplicate planes then you can write a short Python code snippet that this. The simplest is to add a keyboard shortcut for this, which calls your function that adds the 6 extra planes.
I tried to copy the markup plane control points using “GetNthControlPoint”, but it gives an error saying ‘vtkSlicerMarkupsModuleMRMLPython.vtkMRMLMarkupsPla’ object has no attribute ‘GetNthControlPoint’.
Also i tried using “GetNthFiducialPosition” which gives the same type of error.
[0,0,0] is an integer array. You must create a vector of floating-point values for example using np.zeros(3) as it is done in all the examples. [0.0, 0.0, 0.0] would work, too, but it is longer and you cannot do numerical array operations on it directly.
You can create a new node using the scene’s AddNewNodeByClass method. See the script repository for examples.
Thanks a lot, Lasso. I was able to do what I wanted. But when I use the python interactor window, after closing the slicer app; I have to write the code again to work. Is there a way to save this change?
