Abstract:
1. A volumetric computed tomography (VCT) system for producing, in one single rotation, x-ray measurements for reconstructing a plurality of image slices through a portion of a subject positioned along an axis of rotation, the VCT system comprising: an x-ray source array having a plurality of source positions for producing x-rays emanating from each of the source positions, wherein the x-ray source positions are arranged in a two-dimensional array having an extent in the direction of the axis of rotation; an x-ray detector array for acquiring x-ray measurements for each of the source positions separately, the x-ray detector array including x-ray detector elements that are spaced one from the other in the direction of the axis of rotation; and means for rotating the source array and the detector array about the axis of rotation, wherein the x-ray source array and the x-ray detector array have comparable extent along the direction of the axis of rotation.
