摘要： Disclosed is a CT imaging method and system. The method includes: CT scanning an object with a dual-energy CT system to obtain a first complete set of projection data in a first scan mode, and to obtain a second incomplete set of projection data in a second scan mode; reconstructing a first attenuation coefficient image of the object from the first set of projection data, and extracting, from the first attenuation coefficient image, prior structure information of the object indicating edge intensity; and reconstructing a second attenuation coefficient image of the object from the second incomplete set of projection data using the extracted prior structure information as a constraint. With the method using the prior structure information of the imaged object as a constraint in reconstruction, it is possible to dramatically reduce an amount of data required for reconstruction, and achieve satisfactory effects even with ill-conditioned problems of limited-angle and inner reconstruction.

摘要： A millimeter wave three dimensional holographic scan imaging apparatus and a method for inspecting a human body or an article are disclosed. The apparatus comprises a first millimeter wave transceiver module, a second millimeter wave transceiver module, a first guide rail device to which the first millimeter wave transceiver module is connected in slidable form, a second guide rail device to which the second millimeter wave transceiver module is connected in slidable form, a driver configured to drive the first/second millimeter wave transceiver module to move along the first/second guide rail device, and a constrainer configured to constrain kinematic relation between the first and the second millimeter wave transceiver modules such that they only move in directions opposed to each other. They may increase scan speeds, improve scan stability, reduce scan operations and enhance the reliability of the apparatus.

摘要： Methods and devices for inspecting liquid are disclosed. According to the method, it is firstly determined whether the package of the liquid is transparent, semi-transparent, or opaque; in a case that the package of the liquid is transparent or semi-transparent, Raman spectrum analysis is implemented by a Raman spectrum module on the inspected liquid to judge whether the inspected liquid is dangerous or is suspected; and in a case that the package of the inspected liquid is opaque, the inspected liquid are inspected by using an X-ray dual-energy scanning technology to judge whether the inspected liquid is dangerous or is suspected. The above solution has advantages that the inspection speed is high, the material can be recognized, it is suitable for various packing materials with various shapes, the accuracy of the inspection result is high or the like. Therefore, the solution is suitable for security inspection in public places with high security inspection requirements, complicated inspected liquids, high personnel flow rate or the like.
