To start with, have a look at the Curves2DExtractor program in
InsightApplications.  It is described here:

If you don't already have it, you can download the InsightApplications
source from the usual place:

This technique uses a fairly typical approach, using a local Hessian to
detect ridges.  Have a look at the papers by Stephen Aylward and Elizabeth
Bullitt for a good description of vessel extraction, and citations of other
related papers.
