A means is provided for enabling easy identification of baggage in which one or more hazardous item is detected. An inspection system is equipped with a first conveyor, inspection device, cover, camera, controller and display. The first conveyor transports baggage to the inspection device. The inspection device captures transmitted-light images of the baggage using light that transmits through the baggage. The cover covers a transport path of the baggage to prevent a hand of a visitor from being inserted into an image shooting area where electromagnetic waves that are harmful to the human body are irradiated. The camera captures visible-light images of the baggage using visible light. The controller controls the first conveyor, inspection device, camera and display. Under control of the controller, the display simultaneously displays a transmitted-light image and a visible-light image of the baggage.

A technique is provided to enable a baggage holder to smoothly place baggage on a conveyor belt. An inspection device inspects the baggage of a visitor using x-rays. A belt conveyor transports the baggage to an inspection device. On the surface of the belt, plural marks are printed at predetermined intervals along the transport direction. When the belt conveyor drives the belt, the marks move in the transport direction at the transport speed of the belt. When placing baggage on the belt, the visitor can easily perceive the status of the belt, such as its transport direction and speed. The inspection device may have a light emitter near the loading position where baggage should be placed on the belt, and the color of light from the light emitter may change to notify the visitor when baggage should be placed on the belt.

Scanning systems for performing computed tomography scanning may include a stator, a rotor supporting at least one radiation source and at least one radiation detector rotatable with the rotor, and a rotator operatively connected to the rotor to rotate the rotor relative to the stator. A conveyor system may include a respective conveyor extending through the rotor of the scanning system. A control system operatively connected to the scanning system and the conveyor system may be configured to cause the rotor, the respective conveyor, or both to operate at a first operating speed when a wear threshold of the at least one scanning system and the respective conveyor system has not been reached and to cause the rotor, the respective conveyor, or both to operate at a second, lower operating speed when the wear threshold of the at least one scanning system and the respective conveyor system has been reached.

A sample inspection system contains a source of electromagnetic radiation and an apparatus that includes a beam former, a collimator and an energy resolving detector. The beam former is adapted to receive electromagnetic radiation from the source to provide a polygonal shell beam formed of at least three walls of electromagnetic radiation. The collimator has a plurality of channels adapted to receive diffracted or scattered radiation at an angle. The energy resolving detector is arranged to detect radiation diffracted or scattered by a sample upon incidence of the polygonal shell beam onto the sample and transmitted by the collimator.

A baggage screening module including a baggage screening device; and a transportable container for housing the baggage screening device. The baggage screening device is operable within the container to screen baggage, and the baggage screening module is moveable as a unit to a place of use.

A method includes receiving distributed sensing information on one or more characteristics associated with a subject from sensors distributed between a starting location spaced from a resolution location and the resolution location, the resolution location including a targeted screening area, the characteristics being obtained from the sensors observing a plurality of candidate subjects including the subject; determining, based on the information on the characteristics, which category of a plurality of categories is to be associated with the subject for a targeted screening process to be performed in which respective categories correspond to different thresholds applied in the targeted screening process; and electronically communicating information for the category associated with the subject to an electronic device, to direct the subject to a location of the targeted screening area which corresponds to the category, for performing the targeted screening process of the subject corresponding to a threshold associated with the category.

According to an embodiment, a conveyance apparatus includes an upstream-side conveyance portion and a downstream-side conveyance portion. The upstream-side conveyance portion is configured to convey a test object from a conveyance direction deviating with respect to a conveyance direction of a conveyance path of a radiation inspection apparatus to the conveyance path. The radiation inspection apparatus is configured to irradiate the test object with radiation to inspect the test object. The downstream-side conveyance portion is configured to convey the test object from the conveyance path in a conveyance direction deviating with respect to the conveyance direction of the conveyance path. The upstream-side conveyance portion and the downstream-side conveyance portion respectively include a shielding section that is on an extension line of the conveyance direction of the conveyance path and is configured to block the radiation.

A system and method for the accurate determination of a time to fire high energy radiation for security inspection of a cargo vehicle in a drive-through inspection portal. The system includes at least two sensors, one of which is positioned at an entry to the portal, and the other is positioned just after beamline center (BCL). As a driver of the vehicle activates a button at the entry to the portal, the system takes a measurement using one sensor to determine a distance from the driver to a front of the vehicle. As the vehicle reaches the BCL, a measurement is taken by the other sensor in real time and compared with the measurement taken at the entry. A user defined offset is then applied to determine how far behind the driver should the high energy radiation be fired.

In one embodiment, a charged-particle trajectory measurement apparatus for measuring a trajectory of a cosmic ray muon as a charged particle includes: a plurality of detectors, each of which generates a detection signal at the time of detecting a cosmic ray muon; a signal processing circuit that processes the detection signal from the detector; a time calculator that calculates the generation time point of the detection signal from the detector on the basis of the signal outputted from the signal processing circuit; a trajectory calculator that calculates the trajectory of the cosmic ray muon on the basis of the generation time point of the detection signal and the positional information of the detector having detected the cosmic ray muon, wherein the signal processing circuit and each of the detectors are integrally configured by being coupled to each other.

An X-ray image generation device includes a moving mechanism that moves an object relative to a grating part in a direction crossing X-rays emitted toward the grating part. The grating part includes N (2≤N) regions along the direction of movement by the moving mechanism. A cyclic direction of a grating structure in each of the plurality of gratings belonging to an ith (1≤i≤N−1) region out of the N regions and a cyclic direction of a grating structure in each of the plurality of gratings belonging to an (i+1)th region out of the N regions are different directions. The plurality of gratings are configured so that moiré interference fringes generated in the N regions have a cyclic intensity fluctuation measurable by the detector and of at least one cycle or more in the direction of movement by the moving mechanism.
