How to calculate an angle?

i need to now, how to calculate an angle in the last version of slicer, thanls

In Slicer Preview Release that you download on November 4, 2019 (or later), you can add angle measurements by selecting angle markups on the toolbar and clicking in the viewers. You can see the angle values in 3D views and in Markups module.

Thank you very much, another question, do you know how to calculate the position of the angiograph, to calculate the angulation I need to get a better image?

Can your angio system do 3D reconstruction or do you have a 3D angio CT image? If yes, then you can determine optimal viewing angles from that.

If you only have access to 2D imaging then it is up to you to find the optimal viewing angle.

I cannot load DICOM images, the program closes automatically, how do I solve this problem? Thank you.

Maybe you run into this issue. Download the current Slicer Preview version, open Application Settings in Edit menu. In DICOM section, change “Database location” to a new empty folder.

Excellent, it worked…

What Slicer version did you use before? Were you prompted to update your database when you first opened it with Slicer Preview Release?

By any chance, could you share with me the content of the previous dicom database folder so that we can investigate why opening it crashed the application? (you can send me private message by clicking on my name and then on the mail icon)

  • What Slicer version did you use before? The Stable release for windows 4.10.2

  • Were you prompted to update your database when you first opened it with Slicer Preview Release? No

  • By any chance, could you share with me the content of the previous dicom database folder so that we can investigate why opening it crashed the application? I deleted the previous version and the folders. But if you need another kind of information I will gladly send it to you

Is there a way to create a centerline like the one in the image?
