    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： The present disclosure discloses a scanning imaging system, comprising a transportation apparatus (40), a first imaging system (10), and a second imaging system (20). A distance between a ray beam (14) from a first ray generator (11) of the first imaging system (10) and a ray beam (24) from a second ray generator (21) of the second imaging system (20) in the transportation direction is roughly L. A controller (33) is configured to acquire, based on a count value of an encoding counter module (32), a correspondence relationship between data in a position of the inspected object (A) in the transportation direction which is collected by the first imaging system (10) and data in the position of the inspected object (A) in the transportation direction which is collected by the second imaging system (20), wherein a difference between a count value of the encoder (30) corresponding to the data in the position which is collected by the first imaging system (10) and a count value of the encoder (30) corresponding to the data in the position which is collected by the second imaging system (20) is roughly L/D. The present disclosure can achieve alignment of the DR data image and the CT data image in a simple manner.
