摘要： The present disclosure discloses an image display method in a CT system. The method comprises: implementing CT scanning on an inspected object, to obtain CT projection data; organizing the CT projection data according to a predetermined interval; extracting basic data from the organized CT projection data by using a fixed angle as a start angle and using 360 degrees as an interval; forming a DR image based on the extracted basic data; reconstructing a three-dimensional image of the inspected object from the CT projection data; and displaying the DR image and the reconstructed three-dimensional image on a screen at the same time. In the solution, the CT data is processed to obtain DR data. After the DR data is obtained, a DR image is obtained directly using a DR data processing algorithm. This enables an image recognizer to more accurately and more rapidly inspect goods carried by a passenger using the existing experience in image recognition of the DR image.

摘要： Provided is a method of verifying an authenticity of declaration information. The method includes: acquiring a machine-detected radiation image (22) obtained by scanning a container (20) loaded with an article; acquiring a declaration information (21) for declaring the article in the container (20); performing an identification on an image information of the article in the machine-detected radiation image (22) to obtain an image feature corresponding to the machine-detected radiation image (22); performing an identification on a text information of the article in the declaration information (21) to obtain a text feature corresponding to the declaration information (21); screening a declaration category of the article in the container (20) by taking the image feature as an input information and the text feature as an external introduction feature; and determining that the declaration information (21) is in doubt when a declaration category of at least one article in the container (20) does not belong to a declaration category in the declaration information (21).
