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.

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.

A sample inspection system (100) includes an X-ray emitter, a collimator (170) and a first energy resolving detector (180) arranged along a symmetry axis (105). The X-ray emitter generates at least one focused conical shell beam (150) of X-ray radiation comprised of X-ray photons that propagate through a focal point on the symmetry axis downstream of the X-ray emitter. The collimator (170) has one or more channels, each channel being adapted to receive diffracted or scattered radiation propagating either along the symmetry axis, or parallel with the symmetry axis, or both along and parallel with the symmetry axis (105). Upon incidence of the conical shell beam (150) onto a sample (106) the first energy resolving detector (180) detects radiation diffracted or scattered by the sample (106) via the collimator (170).

Described herein are X-ray-based CT systems, specifically those with a stationary X-ray source and a moving object of interest, and methods of using the same, that address limitations in current stationary-source CT, such as scatter contamination and limited scan trajectories. The described systems include a pre-object collimator to form a narrow beam. Scatter contamination is reduced to less than 5% of acquired projections, resulting in high-quality CT images with minimal artifacts, improving diagnostic accuracy and measurement precision. The described system also allows for nonplanar trajectories, providing complete sampling of an object along multiple degrees of freedom.

A spent and/or decommissioned accumulator treatment plant and process, wherein a plurality of objects originating from separate waste collection of spent and/or decommissioned accumulators, nominally comprising lead-acid accumulators and accumulators and objects of a different type, are subject to an X-ray scan. If an analysis of the X-ray scan indicates that an object is not a lead-acid accumulator, and in particular is a lithium-ion battery or accumulator, it is deviated out of the treatment workflow, that comprises grinding the objects and separating lead from other materials.

According to on embodiment, a photon counting CT apparatus includes a hybrid detector and processing circuitry. The hybrid detector includes CT detectors and PCCT detectors. The CT detectors output integral signals concerning the detected X-rays. The PCCT detectors output a count signal for each of a plurality of energy bands concerning the detected X-rays. The processing circuitry estimate a count signal concerning an estimation target CT detector of the CT detectors based on an integral signal output from the estimation target CT detector and a count signal output from the PCCT detector. And the processing circuitry reconstruct an image based on the estimated count signal and the count signal.

Devices and methods for characterization of analyte mixtures are provided. Some methods described herein include performing enrichment steps on a device before expelling enriched analyte fractions from the device for subsequent analysis. Also included are devices for performing these enrichment steps.

A method for analyzing an object includes irradiating the object with incident photon radiation and acquiring an energy spectrum scattered by the material using a spectrometric detector in scatter mode. An energy spectrum transmitted by the material is acquired using a spectrometric detector in transmission mode. A signature (f) is reconstructed representing the object, both from the scatter spectrum measured and from the transmission spectrum measured, and the reconstructed signature thereof is compared with signatures of standard materials.

An X-ray inspection apparatus includes an X-ray source configured to irradiate an article with X-rays in a plurality of energy bands, an X-ray detection unit capable of detecting the X-rays by a photon counting method, an image generation unit configured to generate an overall transmission image corresponding to the X-rays in all of the plurality of energy bands and a transmission image corresponding to the X-rays in some of the plurality of energy bands on the basis of a detection result of the X-rays by the X-ray detection unit, and an inspection unit configured to inspect the article on the basis of the overall transmission image and the transmission image.
