A weighted macropixel signal exhibiting improved signal stability but reduced dose efficiency is determined. A variable specifying the relative signal drift of the unweighted macropixel signal compared to the weighted macropixel signal is determined on the basis of the captured macropixel signal and the weighted macropixel signal. In addition, a relative signal drift filtered with respect to time is determined on the basis of the relative signal drift. Finally, a macropixel signal corrected by the time-filtered relative signal drift is determined. A signal capture device is disclosed. Furthermore, an X-ray detector is described which includes the signal capture device according to an embodiment of the invention. A computed tomography system is also described which includes the X-ray detector."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Noise suppression in the correction of artifacts in CT images","description":"A method is described for correcting a captured macropixel signal of an X-ray detector including a plurality of pixels, combined to form at least one macropixel, to capture discrete signals.
