[Insight-users] How to smooth the segmented surface

[Xiaopeng Yang]

Hi Kent,

 

Do you know any interpolate class in ITK which can generate more slices? For
volumetry, I guess I can use the original data.

 

Thanks,

Xiaopeng

Xiaopeng, 

 

This is a fundamental limitation of your data that can only truly be solved
by reconstructing thinner slices at the time of the scan.  You could
interpolate between images to generate more slices, which would result in a
smoother looking rendering.  If you are trying to make quantitative
measurements (e.g. volume) you must be careful about these kinds of
manipulations though.

Dear Users, 

  

I have tried to segment the liver from 5 mm CT slices. When I tried to
visualize the segmented liver in 3D, I found that the surface of the 3D
liver was discrete, just like stairs. I guess that is because of the 5 mm
interval between CT slices. Do you guys have any good idea how to make the
3D surface of the liver look continuous and smooth? 

  

Thanks, 

Xiaopeng
