Hi everyone, As a beginner of this excellent software, Could anyone teach me how to get the surface of the border, which is the line between white and black region? [NEWCapture]

Hi Gary, Thanks for reaching out. for sake of completness, here are the two other comment you posted in an identical post: I am trying to find the volume rendering of 2d pictures. After click the volume rendering button, it shows me a black solid box, which is not what I want. The goal is to…

You could use the Segment Editor to threshold your image and erase the wanted region, then you could use the Segment Statistics module to get information like the number of voxel. From there, you should be able to compute the surface using metatdata specific to your image (or “picture”) [Se…

Sorry about posting same questions multiple times and Thanks for your reply. The goal is to get the lines between white region and black region, and these lines will form a surface without the black and white region. Here is what I did, I used the threshold to mark the white region, and use Island…

The main problem is that all volume rendering presets assume that background is darker than the object that you would like to see. In your case, the object is dark and background box is bright, therefore you’ll only see a solid box. The simplest is probably to invert your image by using SimpleFilte…

Thanks for your patient and reply Andras.I tried it on my computer, and it works now!!! By the way, Do we have mesh in 3D slicer? Because I would like to collect data of every point on the surface. Thanks for your help again, I do really appreciate it.

Here is what I got from 3D Slicer. By the way, could I do surface mesh rather than volume mesh on this software, and export them as .stl file. Because I would like to use and analyze the surface mesh data.I [Capture]

Once your segmentation is completed, the easiest way to export a surface mesh file is to use Export to files function in Segment Editor module.
