    摘要： A CT apparatus without a gantry is disclosed. The CT apparatus comprises a scanning passage; a stationary X-ray source arranged around the scanning passage and comprising a plurality of ray emission focal spots; and a plurality of stationary detector modules arranged around the scanning passage and disposed opposite the X-ray source. In embodiment, at least some of the plurality of detector modules are arranged substantially in an L shape, a semicircular shape, a U shape, an arc shape, a parabolic shape, or a curve shape when viewed in a plane intersecting the scanning passage. The present invention ensures that the stationary gantry type CT system has a small size, and a high data identification accuracy.

    摘要： The present invention discloses a detecting method of the article detection apparatus composed of an individual DR subsystem and an individual CT subsystem, the method comprising: obtaining a first projection data on ray attenuation coefficient by using the DR subsystem to project the A-layer of an article at a first projection angle, and obtaining a second projection data on ray attenuation coefficient by using the CT subsystem to project the A-layer of the article at a second projection angle different from the first projection angle; and judging whether the A-layer of the detected article exists a dangerous article based on the first projection data and the second projection data so as to obtain a first judgment on the A-layer of the detected article. In the present invention, by combining the projection data of the DR subsystem and the projection data of the CT subsystem, the data information to be used to judge the detected article is greatly increased, therefore, both the detection accuracy and speed are improved.

    摘要： Embodiments of the present invention provide a photoelectric switch for detection of an object. The photoelectric switch comprises: a light transmitter unit comprising plural light transmitters configured to emit plural light signals; a light receiver unit comprising plural optical fiber receivers in one-to-one correspondence with the plural light transmitters and configured to receive the plural light signals and to merge plural light signals, wherein an object detection area is defined between the plural light transmitters and the plural optical fiber receivers; a photoelectric conversion unit connected to the optical fiber receivers and configured to perform photoelectric conversions on the merged light signals outputted by the optical fiber receivers so as to generate an electric signal; and a control and processing unit connected to both the light transmitter unit and the photoelectric conversion unit, and configured to control and process the light signals and/or the electric signal. Embodiments of the present invention also provide a method for operating the abovementioned photoelectric switch.
