Method for the automatic centering of an object to be examined by a tomodensitometer using a fan-shaped beam, and tomodensitometer adapted for this method

摘要

computed tomography (ct) image of a drawing cut an object by using the results of a calculation by computer control signals from a line sensor (5) arranged in array in front of.(4) x-rays.;in a program is sent to the center computer (19) for the development of the direction and the length of the object to be examined is moved so that it is within the range 2(3).in order to reduce or eliminate the amount of radiation received during the life cycle approach.a screen (12) is placed between the source (4) and the body (8) to explore hidden rays except those required to hit the end sensors (17, 18).
