I've seen your topic and I'm interested because I've tried to do the same thing by the past with the result of a topographic 3d scanner (topology of a cave). I've not coded anything, just using some software, but not with good result, so I gived up. Anyway, I've seen some good 3d models that let me think there's already some 3d software that is doing the job, but not freely available by now. They compute what is knows as a Delaunay Triangulation, you surely already know that. But first (or after), it could be useful to reduce the point number. There's also some good algo to do that. In your particular case, I imagine there's some thickness of the organs that should help to determine if you're "inside" or "outside". At this point, the polygon (with a normal) and the closed shape seems necessary to me...
