Lung vessel using CIP module

Im a med student and pretty new about 3D Slicer.
I want to calculate lung vessel BV5/TBV and PA:A.
Recently i have been read this journal, Radiographic Pulmonary Vessel Volume, Lung Function, and Airways Disease in the Framingham Heart Study - PMC as a reference, but i still don’t know how to do it.

Can you help me explain step by step how to generate 3d model of lung vessel using CIP module, then calculate BV5/TBV and PA:A?

Many thanks.
