  • Patent number: 9910184
    Abstract: The present disclosure discloses an alignment system and an alignment method for a container or vehicle inspection system, and an inspection system. The inspection system comprises comprising an ray source, a collimator, a detector arm and a detector module mounted on a detector arm, the ray source, the collimator and the detector module are arranged to form an inspection passage, a ray beam emitted from the ray source passes through collimator and irradiates onto an inspected object, and an attenuated ray beam is collected by the detector module so as to complete inspection. The alignment system comprises a measuring module arranged to receive the ray beam emitted from the collimator and to measure the ray beam so as to determine positions and orientations of the ray source and the collimator. With the alignment method, alignment between a center point of the ray source, a central line of a detector tip and a central line of the collimator may be more accurately measured.

  • Publication number: 20170023697
    Abstract: Disclosed is a method and device for estimating weight of an object to be inspected in an inspection system. An effective atomic number and a high-energy gray value of the dual-energy corresponding to each pixel of the object to be inspected are obtained by a dual-energy radiation scanning. A mass-thickness value for a corresponding pixel is obtained from a pre-created mass-thickness attenuation curve by utilizing the effective atomic numbers and the high-energy gray value of the dual-energy for respective pixels. Weight information for at least a part of the object to be inspected is calculated by multiplying the mass-thickness value by the area of the pixel. Such a method may accurately calculate the weight of the object to be inspected and save the cost for a conventional weighing hardware.

  • Patent number: 9453935
    Abstract: The present invention discloses a gantry configuration for a combined mobile radiation inspection system comprising a first arm frame, a second arm frame and a third arm frame. The first, second and third arm frames define a scanning channel to allow an inspected object to pass therethrough. The gantry configuration for the combined mobile radiation inspection system further comprises a position sensing device configured to detect a position error between the first arm frame and the second arm frame; and a controller configured to control a moving speed of at least one of the first arm frame and the second arm frame based on the detected position error, so that the position error between the first arm frame and the second arm frame is equal to zero.

  • Patent number: 9448188
    Abstract: The present invention discloses a vehicular radiation inspection system comprising a mobile vehicle body, a detection arm, a radiation source and a detector. The vehicular radiation inspection system further comprises a following mechanism separated from the detection arm. The following mechanism contains radiation protection material, and the following mechanism follows the detection arm to move in a non-contact manner during inspection of the inspected object, so as to prevent radiation leakage. In the present invention, it does not need to infuse radiation protection material having a high density, such as lead, into the detection arm. Therefore, it can effectively decrease the weight of the detection arm, and it does not need to provide a balance counterweight on the mobile vehicle body on which the detection arm is carried, thereby effectively solving the problem that the vehicular radiation inspection system has an excessively large mass.
