title: Optical holography in ultrasonography.
abstract: Three techniques for producing three-dimensional ultrasonograms have been investigated. Of these, the optical holographic technique appears to have the advantages of simultaneous viewing of all levels and directions. The effects of magnification, gray scale manipulation, and more expeditious means of producing such holograms remain to be investigated.
