Hi all,

I’m attempting material mapping for mechanical properties in bones. I’ve previously achieved this in MITK-Gem by correlating Hounsfield Units (HU units) with bone density, followed by computing the elastic modulus. Now, I’d like to replicate a similar process in 3D Slicer.

I segmented a femur from a CT scan, meshed it using the Segment Mesher extension, utilized probe volume with a model for mapping, and employed segment statistics to compute the minimum, maximum, and mean values of HU units.

How can I proceed to obtain material mapping or bone density and apply the same equation or a similar method as in the MITK-Gem process? Does anyone have any ideas?
