专利汇可以提供Cinefluorographic holography专利检索，专利查询，专利分析的服务。并且Two motion picture cameras are arranged to photograph the fluoroscopic image derived from two respective X-ray or other energy beams which pass through a subject at respectively different angles. The motion picture films are developed and used in steroscopic pairs to make holograms on a third motion picture film. The information on the third film provides a three dimensional motion picture holographic image of the subject.，下面是Cinefluorographic holography专利的具体信息内容。
1. In a radiographic system, the improvement comprising: a first generator for projecting a beam of radiographic energy through a subject, a second generator for projecting a second beam of radiographic energy at a prescribed angle from said first beam through said subject, a first camera means and a second camera means positioned to intercept said first and second beams respectively and to produce a stereoscopic paiR of images of said subject, projecting means for combining said stereoscopic pair of images into a single dynamic three dimensional radiographic image of said subject to enable observation of the functions of internal organs or elements of said subject in a selected time scale, a first and a second image intensifier means positioned before said first and second respective camera means to intercept said beams and present intensified images of said subject to said camera means, rotatable mounting means for mounting said generators, said camera means, said image intensifier means, and said subject, whereby said subject may be moved prescribed amounts with respect to said generators, camera means, and image intensifier means to present different aspects of said subject to said cameras, said projecting means comprising hologram means for combining said stereoscopic pair of images into an interference pattern to form a hologram, and readout means for deriving a dynamic three dimensional radiographic image from said hologram, said camera means comprising a pair of motion picture cameras, said hologram means comprising means for forming a sequence of holograms on a sequence of frames of motion picture film, said readout means comprising means for deriving a dynamic three dimensional radiographic motion picture image of said subject from said sequence of holograms, said hologram means including laser means for providing coherent light beams for forming said holograms and for deriving said three dimensional radiographic motion picture image, said rotatable mounting means comprising a first rotatable platform, means for mounting said subject on said platform, a first rotatable ring surrounding said platform and concentric therewith, means for mounting said generators, said image intensifier means, and said camera means on said first rotatable ring, a second rotatable platform fixed to said first platform and rotatable therewith, a second rotatable ring surrounding said second rotatable platform and concentric therewith, said second rotatable ring being fixed to said first rotatable ring and rotatable therewith, said hologram means comprising motion picture holographic means for combining information on a pair of films from said first and second motion picture cameras into a holographic interference pattern on a third motion picture film, said pair of films being mounted on said second rotatable platform, said third film and said laser means being mounted on said second rotatable ring.
