A detector for an X-ray computed tomography apparatus has a number of detector elements b1 . . . b10 separated from one another by septa. In order to fashion the detector especially universally, the widths of the detector elements are selected such that a channel occupancy combination from the following group can be realized: [20×b1 or 20×b2 or 16×b4], [16×b1 or 16×b2 or 12×b4], [8×b1 or 8×b2 or 8×b4 or 8×b6], [4×b1 or 4×b2 or 4×b4 or 4×b8 or 4×b12], [8×b1 or 8×b2 or 8×b5], [4×b1 or 4×b2, 4×b4 or 4×b10].
