3D scanning leads?

Has anyone here any acquaintance with techniques for acquiring a 3d scan -that is, a DXF or whatever of a 3d object's surface with all its "topography", at least as seen from one direction? I'm interested in, say, source objects that would fit within one cubic foot, at a resolution of up to 100 dpi. I know that reconstructive plastic surgeons have such scanners, but I'm told they start in six figures. How much processing would be needed to do it with a 180-degree "wraparound" set of photographs, using an appropriate light source at a known distance for each? Or take one time exposure from the front as strobes go off behind spaced slits to either side? Or best of all, some kind of small-scale rastering radar — oops, I think I'm creeping back into six figures… I'd be very grateful for any leads to publications, people, or firms involved in this area.
