De-populated detector for computed tomography and method of making same

A computed tomography (CT) detector array comprising:

• a central detecting region comprising a plurality of central region x-ray detecting cells filling the central region, wherein the central detecting region is configured to have a z-dimension in a slice direction and an x-dimension in a channel direction;
• a first detecting wing comprising a plurality of first wing x-ray detecting cells filling the first wing and and configured to have a z-dimension in the slice direction less than the z-dimension of the central detecting region, the first detecting wing positioned along a first side of the central detecting region, wherein each first wing x-ray detecting cell of the plurality of first wing x-ray detecting cells is of a different type than each central region x-ray detecting cell of the plurality of central region x-ray detecting cells;
• and
• a second detecting wing comprising a plurality of second wing x-ray detecting cells filling the second wing and configured to have a z-dimension in the slice direction less than the z-dimension of the central detecting region, the second detecting wing positioned along a second side of the central detecting region opposite the first side in the x-dimension.

A method of manufacturing a computed tomography (CT) detector array comprising:

• assembling a first detecting wing comprising a first plurality detecting cells filling the first detecting wing and configured to acquire a first quantity of CT slices during a scan;
• assembling a central detecting region such that the first detecting wing is coupled to a first side of the central detecting region, wherein the central detecting region comprises a second plurality detecting cells filling the central detecting region and of a different type than the first plurality of detecting cells, and wherein the central detecting region is configured to acquire a second quantity of CT slices during a scan greater than the first quantity of CT slices;
• and
• assembling a second detecting wing comprising a third plurality of detecting cells filling the second detecting wing such that the second detecting wing is coupled to a second side of the central detecting region opposite the first side in a channel direction, wherein the second detecting wing is configured to acquire a third quantity of CT slices during a scan less than the second quantity of CT slices.
