Edit existing segments without the original volume

Hi Have few segmented bones which are not correctly segmented. The outline has holes. I would like to correct them by solidifying them, correcting the outline. However I do not have the original 3D CT volume for these. Is there a way I could do this please

If you are familiar with Meshlab, that might be the fastest option. You can use:

  • Filters–>

  • Remeshing, Simplification, and Reconstruction–>

  • Surface Reconstruction: Screened Poisson

  • Try different Reconstruction depths: 8, 9, or 10.

In Slicer, you can try the Fill Holes tool in the Surface Toolbox. You’re missing quite a bit though.

Thanks for your reply,

Yes I think its quite challenging to fill without the original volume.
