New module for cross-section area measurement

We have added a new module for measuring 2D cross-section area of segmented structures. User can choose measurement axis direction and results are available both as table and plot.

It is available for latest Slicer Preview Release (Slicer-4.11) in Sandbox extension (in Examples category). After the extension is installed, the “Segment Cross-Section Area” module will show up in Quantification category.

Thanks for @hherhold for developing the original version of the module.

Any comments and suggestions are welcome.


Hi Andras,

Thanks for polishing this up and making it a real module. I learned a lot from doing the original, and even more from reading through your version. Looks awesome.

Thanks again!



The 3D slicer community is sooo warm!
I am finding the way to calculate the 2D segment area and the new version 3D slicer with the new module is releasing! How lucky!
Thank you sooo much!

Hi Hollister,
Thank you so much for the module.
I want to use this modle in a stable version 3D Slicer 4.10, but I don’t know how to install/run it. Would you mind to teach me?


If you want to use this module then you must upgrade to a recent Slicer Preview Release.

Preview Releases work well, they do not have any known issues. However, if you switch to Slicer-4.11 then it is recommended to keep using that and not try to load scenes that are crates with Slicer-4.11 into Slicer-4.10.
