I am using pyRadiomics to analyzed 3D segmentation of tumors.
I noticed the feature " Sphericity" and it is very useful for tumor analysis. Besides this feauture, I want to calculate the " Ellipsoidity" of a tumor.
When the tumor is in the shape of a very prolate or oblate ellipsoid, it would have a low sphericity but the ellipsoidity would be 1. So the featue “Ellipsoidity” could also be very useful.
Can I do this with pyRadiomics?
Thank you in advance.
I don’t know what pyradiomics can compute, but you can use Slicer’s segment statistics module to compute many shape metrics: roundness, flatness, elongation, principal moments, principal axis directions, oriented bounding box diameters, Feret diameter, etc. This allows rich shape characterization, including assessing “ellipsoidity”.
