摘要

THE INVENTION CONCERNS A TRANSLATION-ROTATION TYPE TOMODENSITOMETRY DEVICE AND A METHOD FOR EXPLORING AND RECONSTRUCTING THE IMAGE OF A CA-BODY EXAMINED USING THE DEVICE. / P P THE DEVICE BEHAVIOR, ASSOCIATED WITH A RADIATION SOURCE, N DETECTORS D, D, D ... D RECEIVING N ELEMENTARY BEAMS F, F, F ... JUXTAPOSES, ANGULAR OPEN A, THE USEFUL BEAM F WITH AN ANGULAR OPENING NA AND MEANS FOR COMBINING SIGNALS BELONGING TO THE CONSECUTIVE BASIC ELEMENTARY PROJECTIONS OBTAINED DURING SUCCESSIVE TRANSLATIONS IN ORDER TO OBTAIN, FROM THE NUMBER N, SUPERCONDENT OF ANGULAR SAMPLES PROVIDED DURING A ROTATION OF P RADIANS OF THE SOURCE SET - DETECTORS, THE NUMBER N OF ANGULAR SAMPLES NECESSARY AND SUFFICIENT FOR THE RECONSTRUCTION OF IMAGE. / P P APPLICATION: TOMOGRAPHY WITH FINE RECONSTRUCTION OF IMAGES. / P
