<p>An imaging array has imaging pixels, non-uniform septa, an axial center and a radial perimeter. The septa are positioned in the array such that there is a septum between adjacent ones of the imaging pixels. At least one parameter of the septa varies at least once from the center to the perimeter of the array. The parameter may increase from the center to the perimeter. The parameter may comprise density or atomic number of the septa. Alternatively, the parameter of the septa may be their radial thicknesses which vary relative to the center.</p> |
