摘要：
An X-ray detector, a collimator, a CT apparatus and a method thereof are provided. The X-ray detector comprises a plurality of detector modules which are arranged in an array along a slice direction and a signal channel direction being orthogonal to each other, the array at least comprising a left detection area, a central detection area and a right detection area that are contiguous in the signal channel direction, wherein, in the slice direction, coverage of the left detection area and coverage of the right detection area are complementary and sum of these two coverages is equal to coverage of the central detection area. The collimator comprises a pair of moving shield plates and a fixing shield plate, wherein shape of a window in the fixing shield plate is the same as shape of the array. The CT apparatus comprises the X-ray detector and the collimator.
