From sections of real or hypothetical objects recorded on a film strip, the Synthalyzer instrument generates, on the periodically and uniformly rising surface of a rotating drum, a dynamic three-dimensional synthesis akin to a solid roentgenogram and viewable through 360° azimuth and 80° elevation. In spite of the transparent character of this reconstruction, the internal morphology of dense complex specimens is, understandably, obscured by peripheral detail. To obviate such inherent but hardly acceltable limitation, optical and electronic controls have been incorporated; they provide means for redissecting the synthesis in any planes normal to the spatially frozen projections of the original sections; for removing a portion of the synthesis on one side of the plane of interest; and for dimming the portion on the other side to enhance the plane under investigation, also to serve as an orientation reference. Thus all of the structural details and relations existing within the synthesis can be analyzed. A working prototype has been successfully built and is discussed together with an ancillary device for large audience dissemination of results of the synthalysis.
