Hi,

I have a segemented mask (regions are encoded 0, 1, 2).
I found that the mask can be segmented from image but i don't want to use this segmentation results.
Is there a method to create mesh with segmented results?

Thank you.

Hi Sekeun,

I don't quite understand your question.

You generate a image mask identifying an anatomical feature (e.g. vessel lumen) like in the attached picture. But you don't want to create a segmentation based on the just the mask? You would like to use the mask as a guide for the segmentation? If so then you could add the mask to your original image data and that would allow you to create a segmentation incorporating the mask and original image data.

Cheers,
Dave

Thank you for replying.

I mean i want to create 3d volume mesh to do the fluid simulation.

I have segmented mask which is encoded 0, 1. (512*512*400)

Is there a way to create volume mesh using this segmented mask in simvascular? (or any other program)

Hi Sekeun,

You can create a segmentation of a binary image using the level set 2D segmentation method in SimVascular. You can then create a surface from the segmentation and generate a finite element mesh that can be used for a cfd simulation.

Cheers,
Dave
