Help locating legacy “Expand” / 2D Grow tool for subdural segmentation

Hello,

A while ago, I used the legacy Segment Editor in 3D Slicer, which had a tool that allowed me to expand or grow a segment with a single click. I don’t remember its exact name, but it worked for segmenting subdural hematomas: it would expand the segmentation slice-by-slice in the axial plane, stopping at the skull and without oversegmenting.

I have tried to locate this tool in newer versions of 3D Slicer, and even downloaded some older versions, but I cannot find it. It’s not the Level Tracing tool, but it looked similar to Grow from Seeds, though much simpler and faster.

Can anyone advise:

  • Whether this tool still exists in recent Slicer versions, or

  • If there’s a modern equivalent that behaves the same (2D, slice-by-slice, intensity-guided expansion)?

Thank you for your help!
