Patent ID: 7123681

Claim:
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; and a detector array mounted to the gantry, the detector array comprising: a first plurality of detectors forming a first sub-array having a first end, the first sub-array being disposed with the center line passing therethrough, the first sub-array disposed to receive a first angular extent of the x-ray beam extending in an angular direction from the center lien to the first end; and a second plurality of detectors forming a second sub-array, the second sub-array having a first end, the second sub-array disposed to receive a second angular extent 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 first end of the second sub-array is disposed closer to the center line than the first end of the first sub-array.
