Where to find the data

Hello everyone,

I am looking to have a 3d reconstruction of the colon for simulation.
Sorry if my question may be stupid, I am interested in colon with diverticulitis.

I would also like to know if there are any resources where I can get data for the reconstruction.

As I am new to 3D Slicer, I would like to know if there is a method or extension that allows me to do a quick 3D reconstruction.

Thanks in advance.
