摘要： An inspection system and method, and the system includes: a ray source; a detector assembly; and a conveying device for carrying an aviation pallet cargo. The ray source and the detector assembly are movable in a traveling direction parallel to the central axis relative to the conveying device so that the aviation pallet cargo enters an inspection region, the ray source is translatable between a plurality of scanning positions, and a translation distance of the ray source between two adjacent scanning positions is greater than a spacing between adjacent target spots of the ray source. When the ray source is located at one of the scanning positions, the ray source and the detector assembly move in the traveling direction and the ray source emits X-rays; and when the ray source and the detector assembly move a predetermined distance in the traveling direction, the ray source translates to another one of the plurality of scanning positions.

摘要： Spectroscopy systems require a crystal having specific properties for analyzing a spectrum of a sample, which is typically performed for measuring the presence of one element at a time. A two-dimensional (2D) crystal mount for performing simultaneous spectroscopy measurements includes a crystal holder having multiple rows of crystal mounts. Each crystal mount is positioned and orientated to physically support a crystal at a fixed position and fixed orientation relative to an optical axis. A sample provides radiation to analyzer crystals disposed in the crystal mounts, and a detector may detect radiation reflected from the analyzer crystals, for performing multiple simultaneous spectroscopy measurements.

摘要： The aspects of the present disclosure are directed to a method and system for producing tomosynthesis images of a breast specimen with the capability of attaining images with geometric magnification. In one embodiment, an x-ray source delivers x-rays through a specimen of excised tissue and forms an image at a digital x-ray detector with the resultant image enlarging as the specimen is moved closer to the x-ray source. Multiple x-ray images are taken as the x-ray source moves relative to the stationary breast specimen. In the preferred embodiment, the x-ray source moves in a range from about 350° to and including about 10°. The source may travel substantially along a path that generally defines an arc, or linearly, while the detector remains stationary throughout and the source remains substantially equidistant from the specimen platform. The set of x-ray image data taken at the different points are combined to form a tomosynthesis image that can be viewed in different formats, alone or as an adjunct to conventional specimen radiography. In one embodiment, the system is enclosed or housed within a cabinet X-ray structure.

摘要： A mobile radiography system has a moveable transport frame configured to travel across a floor. An adjustable support structure is coupled to the moveable transport frame and an x-ray source is coupled to the adjustable support structure. A power transmitter emits wireless power signals to a digital detector to charge a battery therein. Power signal receiving circuitry in the detector receives the wireless power signals to generate recharging current for the battery.

摘要： A method for analyzing an object, includes irradiating the object with incident photon radiation, acquiring a spectrum transmitted by the object using a spectrometric transmission detector, determining at least one first property of the object from the transmission spectrum, verifying that at least one doubt criterion relating to the first property of the object is met, and translating the fact that the object contains a material that is potentially dubious for the application under consideration. A second part, carried out only when the doubt criterion is met, includes acquiring an energy spectrum scattered by the object using a spectrometric scattering detector at an angle of 1° to 15°, and determining a second property of the object from at least the scatter spectrum and comparing at least the second property of the object with properties of standard materials stored in a database to identify the objects composition material.

摘要： The present invention provides a digital x-ray radiographic imaging system. The system is based on a photoconductive detector and an electro-optic light modulator, where the photoconductive detector layer absorbs x-rays that have passed through an object to form an exposure of the object. The absorbed x-rays create a static optical image, which is stored in the electro-optic light modulator, allowing the capture of the optical image to continue over longer time. The optical image is digitized using a scanning system and an external light source. The image is then processed and stored by a computer. After the optical image is recorded, an erasing mechanism is used to reset the system before a new exposure is made.
