To shorten a waiting time for a belongings inspection, the present invention provides an inspection system 10 including: an electromagnetic wave transmission/reception unit 11 that irradiates an electromagnetic wave having a wavelength of equal to or more than 30 micrometers and equal to or less than one meter, and receives a reflection wave; a detection unit 12 that performs detection processing of detecting an abnormal state, based on a signal of the reflection wave; a decision unit 13 that decides, for an inspection target person from which the abnormal state is detected, whether to perform a secondary inspection at a place or perform a secondary inspection later; and a registration unit 16 that registers, in association with a result of the detection processing, identification information about the inspection target person decided that a secondary inspection is performed later.

A linac-based X-ray system for cargo scanning and imaging applications uses linac design, RF power control, beam current control, and beam current pulse duration control to provide stable sequences of pulses having different energy levels or different dose.

Provided is an X-ray inspection apparatus that can inspect an object to be inspected with high sensitivity by using a multiple-stage X-ray sensor without widening a slit of a collimator, and can prevent the apparatus from becoming large-sized due to prevention of X-ray leakage. An X-ray inspection apparatus includes an X-ray irradiation portion having an X-ray tube generating an X-ray, an X-ray sensor having detection element arrays in a plurality of stages in a carrying direction, the detection element arrays each formed of a plurality of detection elements linearly arranged in a main scanning direction orthogonal to the carrying direction on a plane parallel to the carrying surface of an object to be inspected, a collimator restricting an X-ray irradiation region for the X-ray sensor, and an imaging condition input section that designates one or more detection element arrays to be used for inspection.

Disclosed herein is a system for x-ray inspection. The system comprises an x-ray emitter. The system also comprises an x-ray sensor array comprising a first x-ray sensor, a second x-ray sensor adjacent the first x-ray sensor, and a coupler movably coupling the first x-ray sensor to the second x-ray sensor. The first x-ray sensor is movable into a plurality of orientations relative to the second x-ray sensor via the coupler. The system further comprises an imaging device to generate an inspection image based on information from the x-ray sensor array.

An X-ray imaging inspection system for inspecting items comprises an X-ray source 10 extending around an imaging volume 16, and defining a plurality of source points 14 from which X-rays can be directed through the imaging volume. An X-ray detector array 12 also extends around the imaging volume 16 and is arranged to detect X-rays from the source points which have passed through the imaging volume, and to produce output signals dependent on the detected X-rays. A conveyor 20 is arranged to convey the items through the imaging volume 16.

A method for the inspection of contained flowable materials within containers, such as detecting an explosive liquid in a luggage, and an apparatus for performing the method are described. The method includes the steps of: performing a radiation scan, using X-rays or Gamma rays, of a target item container of contained flowable material in a radiation scanning system to derive a spatially distributed and spectroscopically resolved measured dataset of the intensity of radiation emergent from the target item; considering the spatially distributed and spectroscopically resolved dataset of transmitted radiation intensity to be nominally determined in accordance with a relationship: [O].Math.[]=[] where the operators [] and [] define, respectively, physical parameters describing the liquid and the container and the system response and the operator [O] defines the relationships between the system response and the liquid and container parameters; numerically processing the measured dataset by operator inversion in order to derive a best fit solution of: []=[O].sup.1.Math.[]; and using that derived solution to determine the threat status of the target item.

A foreign object inspection device is provided. The device reduces the risk of a failure to detect a foreign object. A direction normal to a principal surface is inclined with respect to a direction in which an intensity of electromagnetic waves emitted from an electromagnetic wave generating source is greatest.

Scanning systems may include a stator, a rotor supporting at least one radiation source and at least one radiation detector rotatable with the rotor, and a motivator operatively connected to the rotor. The stator, the rotor, the at least one radiation source, and the at least one radiation detector may be located within a housing. A conveyor system may extend through the housing and the rotor. A shielding system including a series of independently movable energy shields sized, shaped, and positioned to at least partially occlude a pathway along which the conveyor system extends may extend from an entrance to the housing, through the rotor, to an exit from the housing. A control system may be configured to cause the shielding system to automatically and dynamically move individual energy shields in response to advancement of one or more objects supported on the conveyor system.
