After using Probe volume with model, is there any way that I can export the HU values of the elements in a readable format? I need them for FE analysis.

p.s. I can see that slicer.util.array() can be used for reading values on each slice, but I’m not sure about how to read the values for the volume elements.

I’m not sure what format the FE analysis requires, but you should be able to access the per-vertex values with something like arrayFromModelPointData(n, "NRRDImage") where n is your model node and NRRDImage is your array name from Probe Volume with Model. Then you can write it out in whatever format you need.

Thank you Steve for your reply. Yes, then I can use the nodal values to calculate the values at integration points that I will need in FE analysis.

For completeness of our FE, is the source code for Probe volume with model available, so that I can look at the algorithm for calculating the nodal values?
