Patent number: 10650783Abstract: 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.Type: GrantFiled: June 21, 2018Date of Patent: May 12, 2020Assignee: VOTI INCInventors: William Awad, Simon Archambault

Patent number: 10595804Abstract: A control unit acquires first radiographic image data and second radiographic image data and derives bone density from an image of a derivation region of a DXA image which is a difference image between a first radiographic image and a second radiographic image. Then, the control unit derives an evaluation value of the accuracy of derivation of the bone density, on the basis of at least one of the first radiographic image, the second radiographic image, and a bone part ES image, a soft part ES image, and a DXA image which are generated using the first radiographic image and the second radiographic image.Type: GrantFiled: May 9, 2018Date of Patent: March 24, 2020Assignee: FUJIFILM CORPORATIONInventor: Takashi Tajima

Patent number: 10564113Abstract: A method for identifying a material contained in a sample. The sample is subjected to irradiation via ionizing electromagnetic radiation, for example X-rays. The sample is inserted between a source emitting the radiation and a spectrometric detector configured to acquire a spectrum of the radiation transmitted by the sample. The spectrum is subject to different treatment operations to enable classification of the material. The steps are, consecutively: reducing dimensionality, followed by projecting along the predefined projection vectors. Projection makes it possible to establish classification parameters, on the basis of which classification is established.Type: GrantFiled: July 7, 2016Date of Patent: February 18, 2020Assignee: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVESInventor: Caroline Paulus

Patent number: 10545257Abstract: A device and method for material characterization are provided. In one aspect, the method includes detecting packets of radiation emanating from within or passing through one or more items of freight or baggage as a result of irradiation by incident radiation, using a plurality of detectors, each of the detectors being configured to produce an electrical pulse caused by the detected packets having a characteristic size or shape dependent on an energy of the packets. The method further includes processing each of the electrical pulses using one or more digital processors to determine the characteristic size or shape, generating a screening detector energy spectrum for each of the detectors of the energies of the packets detected, and measuring an effective atomic number Z of an unknown material associated with the one or more items of freight or baggage based on the screening detector energy spectra in comparison with calibration measurements.Type: GrantFiled: July 22, 2019Date of Patent: January 28, 2020Assignee: Southern Innovation International Pty LtdInventors: Paul Andrew Basil Scoullar, Christopher Charles McLean, Shane Michael Tonissen, Syed Khusro Saleem, Brendan Allman

Patent number: 10508998Abstract: 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.Type: GrantFiled: May 7, 2015Date of Patent: December 17, 2019Assignee: Lawrence Livermore National Security, LLCInventor: Christopher P.
