Method for combining beam hardening and scattered radiation adjustment in x-ray-computer-tomography of heterogeneous objects, involves moving x-ray source around object

摘要

The method involves moving a x-ray source around an object. A plane designed detector (3) with multiple detector elements is arranged separately, which detects measuring beams from a focus of a x-ray tube (2). An arithmetic and logic unit (10) is provided for vector reprojection calculation by iterative reconstruction and segmentation. A scattered radiation adjustment and a radiation hardness increase adjustment are carried out for variable material components of examining objects.
