Hi,there . I would like know if i can segment the skin of a head CT images with the help of “Segmenteditor module”, i want the outside contour of the head, and there are many tools i
can use, but i don’t know which one can perfectly do this work ?( i know i can simply use
pure manual segmentation method,s like draw、paint… but it is time-consuming)

Any help would be appreciated.

I think a good starting point would be to threshold whole head:

And then use Hollow to get the outer layer:

This requires minor manual processing but should get you a satisfying result within a few minutes:


This segmentation recipe may also help: https://lassoan.github.io/SlicerSegmentationRecipes/SkinSurface/

Also, a new “surface solidify” extension will be added to Slicer very soon, which may further automate the process (see status here).
