Frontal bone thickness within uniform grid

Operating system: Windows 10
Slicer version: 5.2.1
Expected behavior: Calculating thickness within each grid of a uniform grid.
Actual behavior: None

Hi. I segmented a frontal bone. I want to put a uniform grid with 20 roi on the bone surface and calculate the thickness in each of 20 roi. then, I want to colour the grid to show the thickness distribution across the bone surface. Can I do that using 3D Slicer?

You can use VMTK extension’s Extract centerline module for computing thickness, as it can compute not only a centerline but a medial surface and associated radius value.

You get the radius for the entire medial surface, you are not limited to some lower-resolution grid, but if you need these bins then you can compute statistics for each box: get the point position of each model point, determine which box it corresponds to, and add the radius value to that bin.
