Abstract:
1. An imaging device, comprising: a detector for recording an object image using high-energy photons; and an evaluation unit connected to and arranged downstream of the detector for correcting the object image using correction images, wherein the imaging device captures at least two correction images related to the recorded object image, wherein the two correction images are recorded as the object image is recorded and the evaluation unit generates an optimized correction image using the at least two correction images, the optimized correction image related to a point in time when the object image was recorded, wherein the evaluation unit is configured to generate the optimized correction image by deriving an estimation based on the first and second correction images; wherein the evaluation unit process the first and second correction images using a weighting algorithm involving a weighted factor, the weighting factor based on respective time intervals between the point in time when the object image was recorded and the respective points in time when the first and second correction images were recorded.
