Claim 17:
18. A data processing unit communicatively coupled to a memory storing computer-readable instructions, the data processing unit being configured to execute the computer-readable instructions to:
detect a first projection data set using a plurality of first detector units, the plurality of first detector units each including more than a given number of detector elements, wherein the plurality of first detector units are each configured to detect the first projection data set based on spectrally resolved detection of radiation quanta;
detect a second projection data set using a plurality of second detector units, the plurality of second detector units each including, at most, the given number of detector elements, wherein the plurality of second detector units are each configured to detect the second projection data set based on spectrally resolved detection of radiation quanta, and wherein
each of the detector elements is the same size,
the plurality of first detector units and the plurality of second detector units each have a respective size based on a respective number of detector elements incorporated in each respective detector unit, and
the plurality of first detector units have a larger size than the plurality of second detector units;

reconstruct first image data based on the first projection data set;
reconstruct second image data based on the second projection data set; and
combine the first image data and the second image data to generate an image.
