  • Patent number: 10508998
    Abstract: High-contrast, subtraction, x-ray images of an object are produced via scanned illumination by a laser-Compton x-ray source. The spectral-angle correlation of the laser-Compton scattering process and a specially designed aperture and/or detector are utilized to produce/record a narrow beam of x-rays whose spectral content consists of an on-axis region of high-energy x-rays surrounded by a region of slightly lower-energy x-rays. The end point energy of the laser-Compton source is set so that the high-energy x-ray region contains photons that are above the k-shell absorption edge (k-edge) of a specific contrast agent or specific material within the object to be imaged while the outer region consists of photons whose energy is below the k-edge of the same contrast agent or specific material. Scanning the illumination and of the object by this beam will simultaneously record and map the above edge and below k-edge absorption response of the object.

  • Patent number: 10510319
    Abstract: A technique for enhancing an image includes manipulating a base image to highlight pixels showing a particular material based on the energy absorption information of each pixel. In another technique, pixels in a base image are each converted to an output value to produce a converted image. Another technique allows imaging an obstructed object within a base image which is made of pixels, each representing a captured signal from a source emitting a source signal I0. An obstruction region contains pixels representing a combined signal I3 having traversed the obstructed object and an obstructive layer. Knowing a layer signal I2 representing a signal having traversed the obstructive layer outside of the obstruction region, the layer signal I2 may be removed from the combined signal I3, in order to reveal the original signal I1 representing an image of the obstructed object.

  • Patent number: 10463329
    Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an X-ray tube, an X-ray detector and processing circuitry. The X-ray tube exposes an X-ray toward an object. The X-ray detector acquires two X-ray detection data sets by counting X-ray photons, having transmitted the object, in at least two X-ray energy bands depending on a K absorption edge of an X-ray absorber taken into the object. The processing circuitry is configured to input information to specify the X-ray absorber, set the at least two X-ray energy bands based on the input information to specify the X-ray absorber and generate at least one frame of X-ray image data by data processing including subtraction processing of the two X-ray detection data sets. The X-ray absorber has been depicted in the at least one frame of the X-ray image data.

  • Patent number: 10416099
    Abstract: A method for performing x-ray absorption spectroscopy and an x-ray absorption spectrometer system to be used with a compact laboratory x-ray source to measure x-ray absorption of the element of interest in an object with both high spatial and high spectral resolution. The spectrometer system comprises a compact high brightness laboratory x-ray source, an optical train to focus the x-rays through an object to be examined, and a spectrometer comprising a single crystal analyzer (and, in some embodiments, also a mosaic crystal) to disperse the transmitted beam onto a spatially resolving x-ray detector. The high brightness/high flux x-ray source may have a take-off angle between 0 and 105 mrad. and be coupled to an optical train that collects and focuses the high flux x-rays to spots less than 500 micrometers, leading to high flux density.

  • Patent number: 10191181
    Abstract: A multi-channel system for truck scanning, includes an impulse radiation source; and a plurality of detection circuits, each detection circuit comprising a scintillator, a photodiode, a supplemental circuit, an integrator and an ADC, connected in series. A current of the photodiode is proportional to radiation from the impulse radiation source. A data storage device stores outputs of the ADCs and provides the outputs to a computer that converts them to a shadow image of the scanned truck. The supplemental circuit isolates a capacitance of the photodiode from the integrator, filters out low frequency signals from the photodiode, amplifies the signal from the photodiode and reduces a bandwidth of the photodiode seen by the integrator. The supplemental circuit reduces an influence of capacitance of the photodiode on system noise, increases a signal-to-noise ratio of the system, and reduces an influence of photodiode temperature changes on a quality of the scanned image.

  • Patent number: 10078150
    Abstract: A method, system and computer program product for automatically detecting and quantifying materials in containers (e.g., luggage, storage containers, equipment or componentry for processing or handling). An X-ray radiograph of a container is generated. A set of materials of interest (e.g., plutonium, steel) is selected to determine if the object comprises or contains materials of interest. An estimate of the areal densities or thicknesses of each of the selected materials of interest is obtained by minimizing an objective function with respect to the areal densities or thicknesses for each of the selected materials of interest. Adaptive regularization is implemented in the objective function to improve optimization results by adding a constraint to the objective function, where the constraint penalizes the objective function for solutions that do not line up with a prior belief about the solution form (e.g., the solution should not be negative or especially noisy).

    Abstract: An X-ray analysis device includes an electron gun, an X-ray optical member, a first detection unit and a second detection unit, and a distance changing mechanism. The X-ray optical member guides characteristic X-rays emitted from a sample to at least any one of the first detection unit or the second detection unit.

The second detection unit is formed such that counting efficiency is given relative priority over energy resolution in contrast to the first detection unit. The distance changing mechanism changes the distance between each of the first detection unit and the second detection unit and the X-ray optical member in an axial direction of an optical axis of the X-ray optical member.
