@lassoan  
Thank you for your support.

I saw your reply here: [VMTK - cross-sectional perimeter calculation - #4 by chir.set](https://discourse.slicer.org/t/vmtk-cross-sectional-perimeter-calculation/37747/4)  
It seems to describe exactly what I’m looking for.

For example, if I want to get the area and perimeter of the slice shown in the Red window, and the slice intersects both legs, two cross-sections are displayed.  
Even if multiple cross-sections are present, I would like to obtain the area and perimeter for each one as separate closed curves.

I’m not sure what would be the best way to implement this, but if we could select the slice view (e.g., Red, Green, Yellow), run the calculation, and have the area and perimeter results appear in a table, it would be very useful for anatomical measurements.

Thank you again for your support.
