Claim One:
1. A process for generating a tomographic image of a three-dimensional object in a sectional plane (P) comprising: irradiating the object at various angles of incidence (R.sub.1, R.sub.2,. .. ) by means of beams converging toward the sectional plane using at least one radiation source (3); detecting for each angle of incidence, and by means of a transducer (4, 7) having a photosensitive surface, the radiation passed through the object for generating for each of said angles of incidence an electric signal representing an image signal, and processing the various image signals corresponding to the various angles of incidence for the purpose of emitting a synthesized signal representing the tomographic image, said processing step comprising comparing the values of the different image signals at each image point, selecting the image signal value corresponding to the least radiation attenuation for each image point, storing the selected values comprising the synthesized signal representing the tomographic image, and feeding the stored signal to display means (10) for visualizing the tomographic image.
