intensities differences in mesh

Postby rubenmiranda » Tue Jul 24, 2012 11:01 am

Hello,

I have an image of probabilistic tractography performed with another program and I wish to make a mesh of this image (AimsMeshBrain).
But the image has intensity differences (in function of the number of connections per voxel) that I would like to preserve in the mesh. Is it possible?

Thanks in advance

Hi,

A mesh is generally the boundary of an object, this means it is basically used to represent binary objects.
With an intensity image, you can threshold and binarize the image, then make a mesh. You can do so for several intensity thresholds, so as to get a set of meshes, each corresponding to a specific threshold. Then you could use a color and / or opacity code to represent all of them, a bit like what we do for sulcal SPAM models representations in BrainVisa. But I'm not sure it's the best representation for your data.
What would you like to display ?

Denis
