Abstract:
1. A computer tomography medical examination device, comprising: a radiographic source for illuminating an object being medically examined from different projection angles; a detector for detecting a radiation from the radiographic source and recording a projection image of the object; and an evaluation unit connected downstream from the detector for reconstructing a volume image of the object from the projection image and correcting an image error caused by interference effects in the volume image, wherein an uncorrected volume image and a correction volume image are created by the evaluation unit, wherein a corrected volume image is created by the evaluation unit by superimposing the correction volume image on the uncorrected volume image with an user selected weighting function, wherein the evaluation unit creates the uncorrected volume image from the projection image, wherein the uncorrected volume image is re-projected to create a corrected projection image, wherein the correction volume image is created from the corrected projection image.
