Method for producing three-dimensional real image using radiographic perspective views of an object

A method of reconstructing a three-dimensional real image of a radiopaque object comprising:

• preparing a plurality of radiographs of said object by passing a source of penetrating radiation along a known path and irradiating said object at each of a plurality of positions along said path to prepare a plurality of radiographic perspectives;
• generating an object beam of coherent light and illuminating said radiographic perspectives therewith to re-trace the rays thereof in accordance with the geometry in which each of said radiographic perspectives was originally made;
• generating a coherent reference beam;
• holographically recording each radiographic perspective on a holographic recording medium using said object and reference beam;
• and then simultaneously illuminating all of said holographically-stored images with the conjugate of said reference beam.

A method of reconstructing a three-dimensional real image of an object comprising:

• preparing a plurality of radiographs of said object, each from a different perspective by irradiating said object with a source of radiation transmitting rays along predetermined paths to a radiographic recording medium;
• generating a reference beam of coherent light;
• generating an object beam of coherent light;
• passing said object beam of coherent light through ray back-tracing lens means and through said radiographs to re-trace said predetermined paths along which said radiation rays were transmitted;
• illuminating a radiographic perspective with said object beam exposing a section of holographic recording medium to said object beam and said reference beam simultaneously for each radiographic perspective to thereby form a holographically-recorded image of each radiographic perspective containing the same perspective information in the original radiographic perspective;
• and then simultaneously illuminating all of said holographically-recorded images with a beam of coherent light that is the conjugate of the reference beam used to make said holographically-recorded images.

A method of producing a three-dimensional real image of a radiopaque object comprising:

• preparing a plurality of radiographic perspective views of said object by providing a reference beam of coherent light and an object beam of coherent light, and directing said object beam to converge along a known path corresponding to the path of the source used to prepare said radiographic perspective views;
• illuminating each radiographic perspective view with said object beam, each radiograph being spaced from said path at a distance corresponding to the distance from the source of radiation used to prepare said radiographic perspective views to the associated radiograph;
• exposing a portion of holographic recording medium to said object beam and said reference beam at a location between said path and a radiographic perspective view illuminated by said object beam;
• directing a beam of coherent light which is the conjugate of said reference beam on a plurality of said holographically-stored images simultaneously to thereby reconstruct a three-dimensional real image of said object.
