1. A computer-implemented method, the method comprising causing a computer system to execute instructions for: providing a first data set and a second data set, each derived from a common object; providing a first tomographic image object associated with the first data set; providing a second tomographic image object associated with the second data set; generating a multimodal pixon map for pixon smoothing on the basis of the first data set, the first tomographic image object, the second data set, and the second tomographic image object; and outputting the multimodal pixon map.
