Scan effect in nuke?

Sorry for the title first off, I do not know how to describe the effect I am trying to achieve.

Basically i have a green screen shot of a actor and I need to have him walk through a scanner and it visually draws a line around him on a single plane giving the illusion that he is walking through a single laser scanner thing.

Besides hand drawing a roto of the laser starting in say his nose and growing outward, is there some other trick?

If I could get a point cloud for him I could see this working, but it's a static camera.
