A TECHNIQUE FOR THREE-DIMENSIONAL REPRODUCTION OF RADIOGRAPHS

THE USUAL PROCESSES FOR PRODUCING THREE DIMENSIONAL RADIOGRAPH, BASED ON THE COMPOSITION OF A HOLOGRAM MATRIX FROM A SERIES OF INDIVIDUAL RADIOGRAPHS TAKEN FROM DIFFERENT PERSPECTIVES, ARE IMPROVED AND EXTENDED WITH A TECHNIQUE IN WHICH THE INDIVIDUAL RADIOGRAPHS ARE SUCCESSIVELY ILLUMINATED WITH LASER LIGHT THROUGH A DIFFUSING SCREEN WITH A WIDE SCATTERING CHARACTERISTIC. THIS METHOD ENSURES THAT THE LIGHT WAVE EMERGING FROM EVERY POINT OF THE RADIOGRAPH IMPINGES EVENLY ON THE ENTIRE PHOTOGRAPHIC PLATE INTENDED FOR FORMATION OF THE HOLOGRAM. OF IMPORTANCE IS THE POSSIBILITY OF USING A DIFFERENT REFERENCE BEAM TO OBTAIN FROM THE HOLOGRAM MATRIX A REAL THREE-DIMENSIONAL IMAGE OF THE OBJECT X-RAYED. FROM THIS IMAGE, IT IS POSSIBLE TO PRODUCE RADIOGRAPHS OF PLANES WHOSE DEPTHS CAN BE FULLY SELECTED AND ALTERED.
