This would include the surface area of the peritoneal cavity (lining or peritoneum) itself and , if possible, the surface area of the organs inside the peritoneum. Ideally selectively by organ, also if possible. Has this been done? Thanks, Ric

If you [segment](https://slicer.readthedocs.io/en/latest/user_guide/image_segmentation.html) the peritoneal cavity and each organ of interest then you can get the surface areas automatically using Segment Statistics module.
