how to create maximum inscribed Sphere in 3d Image for porous images?

Hello, this is my first time using matlab for my university research.

My task is to create maximum inscribed Sphere for 3D porous image. Do you have any idea or inputs for me?

I have tried creating maximum circle for 2d image and it worked, but i dont know for 3d image.

Any help is appreciated and thank you so much
