Abstract： |
This invention involves radiation detection technology fields, particularly a cargo security inspection method based on helical scan imaging technology, including the application of dual-energy-ray source, turntable, data acquisition modules and main control computer and data processing cargo security inspection system. The method includes: A. rapid spiral scan of the subject, reconstruction the image of physical parameters of the subject; B. judging if image reconstruction has suspects region, if it exists, the implementation of steps C; Otherwise, the end of this process; C. computer tomography the suspects region, reconstruction suspects region sectional images, and according to the redevelopment of the subject sectional images of conducting security checks. The invention can cut scanning time, and save the security checks time on goods, to achieve fast and accurate inspection. In addition, this invention is low cost, and very helpful to the promotion and application. |
