摘要： An X-CT scan system includes a base, an object rotary support, an X-ray generation device and a data acquisition system, wherein one side of the detector is leveled to or beyond the prolong line of the connecting line between the X-ray source of the X-ray generation device and the center of the object rotary support, the length of the beyond portion is less than the radius of the imaging field. The advantage of the invention is in that the invention can reconstruct the entire image of the object by means of X-ray projection data which only covers half of the area of the object. Compared with the traditional CT scan system, half of the detector size can be saved at most. The X-CT scan system is simplified and the projection data amount for scan and computation amount for image reconstruction are also reduced with the reconstructed image quality guaranteed.

摘要： Disclosed is an image reconstruction method in a high-energy dual-energy CT system. The method comprises steps of scanning an objection with high-energy dual-energy rays to obtain high-energy dual-energy projection values, calculating projection values of base material coefficients corresponding to the dual-energy projection values on the basis of a pre-created lookup table or by analytically solving a set of equations, and obtaining an image of base material coefficient distribution based on the projection values of base material coefficients. The method provides a solution for reconstruction with high-energy dual energy CT technology and thus a more effective approach for substance identification and contraband inspection, thereby bringing a significant improvement on accuracy and efficiency in security inspection.
