A detector for an X-ray computed tomography apparatus has a number of detector elements separated from one another be septa forming a detector line. For improving the efficiency of the detector, the septa are arranged according to the relationship:wherein {Sk} is the total number of septum locations,zepsi N is the number of channels,D1 is the smallest width of a detector element,Di=ni Di is the width of the ith subdivision, whereby i>1 and ni>ni-1 apply, andjepsi N is the number of different widths Di.
