| Abstract: | With the ever-changing domestic and international security situations and development of scientific technology, more and more X-ray Computed Tomography security inspection equipments are used in civil aviation. Therefore, it＇s practically crucial to develop the test and evaluation method for this kind of security inspection equipment. Based on the characteristics of civil aviation passenger＇s baggage checking, this paper analyzed and calculated the parameters of Computed Tomography security inspection equipment, and described the test methods and evaluation. Such efforts should be made to promote and expedite the development of security equipments for security check. |
