Abstract:
1. A detector assembly for a computed tomography scanner having an x-ray source to provide an x-ray beam, the detector assembly comprising: a gantry having a center line extending from the x-ray source and dividing the gantry into two substantially equal-sized halves; a first plurality of detectors disposed on a first half of the gantry forming a first sub-array having a first end and a second end, wherein the first end is disposed near the centerline and the second end is disposed further from the centerline, the first sub-array disposed to receive a first portion of the x-ray beam extending in an angular direction from the first end to the second end; and a second plurality of detectors disposed on the first half of the gantry forming a second sub-array, the second sub-array having a first end and a second end, where in the first end is disposed closer to the centerline than the second end, the second sub-array disposed to receive a second portion of the x-ray beam that is adjacent the first angular extent and extends further from the center line than the first angular extent, wherein the second end of the first sub-array is disposed closer to the center line than the first end of the second sub-array.
