if you can make your 3d scanner dump put a text file of the data then you can easily read it into maya (this is exactly what I am doing in my current WIP, see the link in my sig)

It's farily easy to read thru a file and set keyframes etc and i'm sure that it's just as easy to set the points on a curve.

Post again with some more specfics and I'll point you in the right direction.
