摘要： A CT imaging system (1000) is provided, including: a scanning channel (200) disposed in a first direction; a radiation source component (10) disposed on one side of the scanning channel (200), wherein the radiation source component (10) is used to emit radiation beams; a detector component (20) disposed on another side of the scanning channel (200), wherein the detector component (20) is disposed opposite to the radiation source component (10) and used to receive the radiation beams, and the radiation beams forms an imaging region between the radiation source component (10) and the detector component (20), wherein the detector component (20) includes at least two detection regions (21) and at least one blank region (22), the imaging region has a central cross-section of the radiation beams (31) extending through the radiation source component (10), and a position of the detection region (21) and a position of the blank region (22) are complementary with respect to the central cross-section of the radiation beams (31). The CT imaging system (1000) may obtain missing data through algorithm compensation, by means of rotational scanning and based on data symmetry, so as to obtain complete projection data to restore image information of an object to be inspected (100).
