How to describe the position relationship between lung tumor and trachea

Operating system:
Slicer version:
Expected behavior: After the lung and trachea are separated, what parameters describe their position relationship
Actual behavior:

How would you like to describe the spatial relationship? For what purpose? Can you describe the overall goal of your or your project?

Thanks for your help.
I am a radiotherapy physician. I want to analyze the effect of the relative spatial location of central lung cancer and the main trachea on the curative effect, but I do not know how to obtain the spatial location relationship data of lung mass and trachea.
sincere thanks :slightly_smiling_face:

You can get position of each segment as oriented bounding box, center of gravity, principal axes, etc. using Segment Statistics module. This provides you rich spatial relationship information.
