COMPUTED TOMOGRAPHY METHOD, COMPUTER SOFTWARE, COMPUTING DEVICE AND COMPUTED TOMOGRAPHY SYSTEM FOR DETERMINING A VOLUMETRIC REPRESENTATION OF A SAMPLE

摘要

A computed tomography method for determining a volumetric representation of a sample (13), comprising a first reconstruction (22a) for reconstructing first reconstructed volume data (23a) of the sample (13) from first x-ray projection data (21a) of the sample (13) taken by an x-ray system (10), a second reconstruction (22b) for reconstructing second reconstructed volume data (23b) of the sample (13) from second x- ray projection data (21b) of the sample (13) taken by an x-ray system (10), characterized by calculating first individual confidence measures (28a) for single voxels of said first reconstructed volume data (23a), calculating second individual confidence measures (28b) for single voxels of said second reconstructed volume data (23b), and calculating, in a subsequent step (35), at least one resulting set of individual values (36, 37, 38) for each voxel based on said first individual confidence measures (28a) and said second individual confidence measures (28b).
