摘要： A method of transmitting raw data by a data acquisition system in a CT scanning system, wherein the CT scanning system comprises a rotational part of a gantry with at least one raw data backup memory, and wherein the data acquisition system is configured to adopt the at least one backup memory for storing a backup of the raw data. The method comprising: generating the raw data as scanned; storing generated raw data in the at least one backup memory; transmitting the raw data to an operation console in the CT scanning system; and repeating generating, storing, and transmitting of the raw data in the case of an unfinished scan, until the unfinished scan is finished.

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.
