You can use the `Segment Cross Section Area` module in `Sandbox` extension (listed under the Examples category in the Extension manager).

> A new module - “Segment cross-section area” - has been added to Slicer. It can compute cross-sectional area of segmented structures along a chosen axis direction. Results are available both as a table and can be shown in a plot, too. Short demo video: For now, the module is available by installing “Sandbox” extension in the extension manager in a recent 3D Slicer Preview Release. If you have any comments and suggestions then please post it here.
