Hi. I am an interventional cardiologist. Currently I am interested in pre-planning for my intervention. In detail, I want to determine the optimal angles for setting the X-ray views. Is there any extension, or Python codes for displaying these parameter (as I show in the following image). [image] …

[image] cloudman: but an error is reported What is the error? What Slicer version do you use?

@lassoan The error is: >>> sliceViewNode = view.mrmlViewNode() Traceback (most recent call last): File "<console>", line 1, in <module> AttributeError: qMRMLSliceView has no attribute named 'mrmlViewNode' I need to display angles in red slice viewer, the image is 2D, so I modified your 3D viewer…

The script above solves a more complex task: computing C-arm angles from the camera viewpoint in a 3D view. You can use it to find a good angulation that you can just on your C-arm. If you already have an X-ray angiography image sequence then the C-arm angles are already stored in the DICOM series …

I just want to display the C-arm angles in red slice viewer. I found the angles are in the DICOM tags:(0018,1510) DS PositionerPrimaryAngle, (0018,1511) DS PositionerSecondaryAngle. How can I make it display as (LAO/RAO, CRA/CAU) in the red slice viewer?

Does the C-arm move during your acquisitions? Is it enough to show the angles of the for frame of the sequence?

The acquisition process does not move, and each sequence has an angle. I want to display the angle of the sequence after opening a sequence. The angle information is recorded in the Dicom tag, but I don’t know how to display it. [20230425145028]

Would it be sufficient to include the angles in the node name? You can enable showing the buffer name in the slice view corner annotation.

Yes, it’s enough, I just want the angle to be displayed. I don’t know how to get the value of PositionerPrimaryAngle and PositionerSecondaryAngle, and then display it on the red slice viewer. I only know that I can get the angle through the following function by getting those two values: def forma…

The angles could be added to the name of thr image at the time of DICOM import. The importer is this Python script, you can modify it on your computer.

It works, Thank you！ [QQ截图20230506153341]
