Abstract:
A detector for X-ray computed tomography apparatus comprising a plurality of detector elements separated from one another by septa forming respective detector lines in a direction of a rotational axis of said tomography apparatus, said septa being symmetrically arranged with respect to a symmetry plane of each detector line that proceeds perpendicular to the rotational axis, a plurality of said detector lines being arranged next to one another, a predetermined plurality z of channels for acquiring signals generated by the detector elements with one or more of the detector elements being connectable to respective ones of said channels for acquisition of the signals, and the septa being arranged at opposite sides of the symmetry plane according to the relationship: {sk}=&Union;m=1j&it;{&Union;p=-z/2z/2&it;{p&CenterDot;nm&CenterDot;D1}},wherein {sk} is the total number of septum locations,z&egr; N is the plurality of channels, D1 is a smallest width of a detector element, Di=ni D1 is a width of an ith subdivision, with i>1 and ni>niâˆ’1, and j&egr; N is the plurality of different widths Di.
