More Information
Summary:A system for reconstructing a tomogram or a portion thereof of a cross-section of an object. Modified signal profile data obtained by exposing the object to a substantially flat beam of penetrating radiation from different angles and by preprocessing the transmission radiation received at positions respectively corresponding to the different angles of incident radiation is stored in an analogue form into a collection of primary record paths, each of which is uniquely related to an associated angle of incident radiation; whereas such information elements stored in various of said primary record paths as are included in a secondary path that is uniquely defined by position coordinates determinative of the radiation absorption or density of a certain element of the object cross-section, are integrated.
