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?

Good night, currently, does 3D Slicer have any international approval for medical use? regards

14

No, as far as I know. But nothing prevents a user from seeking such an approval. The license has no give back requirement.

You can have Slicer display the Slice intersections. Shift plus mouse movement will allow you to navigate slices.

Slicer has been used clinically in many projects in many countries, as described in thousands of papers that cite Slicer (see a selection here). For each use case, it is your responsibility to ensure that Slicer fits for the purpose and obtain the necessary approvals. See more information in these related discussions:

Yes, and there are several options. Your question has been already forked out to this topic, let’s continue the discussion there: How to define vessel centerline
