A process for the reconstruction of sectional images from detector measuring data of a tomography device

摘要

The present invention relates to a reconstruction methods in the computer - tomography (1), in which an object to be examined (7) by means of a beam of rays (r₁-R₈) is scanned, which, during the scanning of a system axle (5) rotates, wherein initially the absorption coefficient of partial volumes (16, 17, s_si), the of the system axle (5) are furthest removed, are determined and subsequently iteratively the absorption coefficients the closer to the system axle (5) extending at an angle (16, 17, s_si) with consideration of the already calculated absorption coefficient be determined.
