A radiation imaging control apparatus according to an aspect of the present invention includes an image acquisition unit configured to acquire a captured image obtained by capturing an image of a subject, a foreign matter detection unit configured to detect, in a case where a radiation image of the subject is to be acquired, a foreign matter which is likely to appear in the radiation image from the captured image acquired by the image acquisition unit, a warning information generation unit configured to generate warning information regarding image capturing of a radiation image based on the foreign matter detection unit having detected a foreign matter in the captured image, and a display control unit configured to issue a notification based on the warning information.

A method for correctly identifying at least one source, in particular at least one nuclide, enclosed in a human body and/or a container, is provided, the method comprising the following steps: detecting and measuring the at least one source by means of a gamma spectroscopic device; identifying, in a first estimation step, the at least one source by means of a standard nuclide identification procedure for evaluating a measured first spectrum of the at least one source; applying a second estimation step on the basis of the result of the first estimation step, wherein the result of the first estimation step is used for acquiring a plurality of second spectra of the at least one source found by the standard nuclide identification procedure for a plurality of absorption scenarios and for a plurality of scattering scenarios; and comparing the measured first spectrum with a scatter and absorber spectrum obtained from the plurality of second spectra generated in the second estimation step.

The method and device to ensure a safety of people's life and health is based on measurements of spontaneous electromagnetic radiation caused by a deformation from a structure or device, a nucleation and growth of plant cells and living organisms; calculating an energy stored in a portion of the structure or cells based on a measured intensity; performing a comparison of the energy stored with a critical value for the structure and pathological changes in the cells; and indicate a potential failure of the structure or a level of pathological changes based on the performed comparison.

The invention provides a test device for assessing the detection capability of an X-ray system with a medium and/or large tunnel size. The device comprises a support and at least one test module mounted on the support. The device may optionally also comprise a stand which holds the support at a predetermined angle to the horizontal. The test module, or at least one of the test modules, is capable of being used in a test for an aspect of the detection capability.

Apparatuses are provided for evaluating an image quality of an image produced by an x-ray computed tomography (CT) system.

Phase stepping for differential phase contrast and/or dark field x-ray imaging using a switchable grating in which particles in a reservoir are aligned into wall-like x-ray absorbing structures by inducing a standing wave in a medium in the reservoir. The standing wave is modified by a second ultrasound generator that modifies the standing wave such that the pressure nodes of the first standing wave shift position.

An X-ray inspection device including means for ensuring complete imaging of every article that passes through the X-ray inspection device. Methods of using the X-ray inspection device are also described.

The present specification discloses a multi-view X-ray inspection system having, in one of several embodiments, a three-view configuration with three X-ray sources. Each X-ray source rotates and is configured to emit a rotating X-ray pencil beam and at least two detector arrays, where each detector array has multiple non-pixellated detectors such that at least a portion of the non-pixellated detectors are oriented toward both the two X-ray sources.

Various embodiments are directed toward systems and methods relating to security screening. For example, a screening system includes chamber scanners oriented to scan different heights corresponding to different respective portions of a user, to identify whether the user is carrying an item that is to be divested. The screening system also includes a divestment scanner configured to obtain a detailed item characterization of the item divested from the user.
