    摘要： An x-ray detector assembly includes a curved rail and a first plurality of x-ray attenuation plates attached to the curved rail, wherein the plates of the first plurality of x-ray attenuation plates are spaced apart from one another by a first pitch. A second plurality of x-ray attenuation plates are attached to the curved rail, wherein the plates of the second plurality of x-ray attenuation plates are spaced apart from the plates of the first plurality of x-ray attenuation plates by a second pitch greater than the first pitch. A first plurality of x-ray detector cells is also positioned adjacently to the first and second pluralities of x-ray attenuation plates and positioned in a linear arrangement with respect to each other.
