The process of separating regions within a CT scan dataset (usually based on Hounsfield number) is known as
segmentation, and applies to any separation of adjacent tissues based on image density, not just cancellous and cortical
bone.

As noted by some of the responders to the original posting, a software package named Mimics is well suited to the task
of taking you from CT data to meshable solid. Mimics includes segmentation capabilities.

Perhaps a search of the web, using a phrase such as "CT scan segmentation" will lead you to other software that does
this. I'm not ware of any freeware or lower cost software that does this. Perhaps one of the other BIOMCH-L members
would care to chime in...
