摘要：
A cargo security inspection method and system based on spiral scanning, the method including: spirally scanning an inspected object at a first precision to obtain the transmission projection data; judging whether there is a suspect area in the inspected area; scanning at least one slice of the suspect area at a second precision wherein the second precision is greater than the first precision; reconstructing a tomographic image of the at least one slice; and using the reconstructed tomographic image to judge whether there is any dangerous article in the suspect area.
