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.

摘要： The present invention discloses recognizing methods of flaky or blocky prohibited articles, explosives or drugs. Specifically, the method for recognizing flaky prohibited articles, explosives or drugs comprises steps of: (1) reading in tomogram data of an object to be inspected for one tomogram; (2) pre-processing the tomogram data; (3) splitting the pre-processed tomogram data into a plurality of regions that have similar physical properties; (4) analyzing whether each of the split regions is a flaky region; (5) determining whether the flaky region recognized in the current tomogram can be merged with the flaky region detected from the previous tomogram, so as to form a flaky target; (6) determining whether each detected flaky target is complete or finished; (7) repeating steps (1)-(6) and processing each tomogram data layer by layer, until all of the tomogram data have been processed.

摘要： A computer-implemented method for use in analyzing a model of a repetitive structure includes generating a plurality of blocks based on the model such that the blocks are arranged end to end. The method also includes defining at least one boundary condition on an inlet of the model and on an outlet of the model, generating a plurality of constraints to be applied to the blocks to define connectivity between adjacent blocks, defining an inlet state based on the boundary condition and at least a portion of the constraints. The method further includes detecting when a first block passes a trigger plane at the inlet of the model, erasing a state of a second block at the outlet of the model, shuffling the second block to an inlet zone, and resetting the state of the second block to the inlet state.
