  • 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).

  • Patent number: 9396547
    Abstract: A method for increasing the accuracy of a target property value derived from a rock sample is described in which the sample is scanned to obtain a three-dimensional tomographic digital image which can be processed to pore space and solid material phases through a segmentation process. A process is used which revises the segmented volume, e.g., by increasing pore space connectivity, in a manner affecting the target property value that would be derived. Another described method increases the accuracy with which a segmented volume represents a material sample having structure not adequately resolved in an original three-dimensional tomographic digital image. Further, a system for performing the processes, and a segmented digital volume which more accurately represents a sample of a porous media, are described.

  • Patent number: 8895937
    Abstract: The present disclosure provides a convertor for X-ray radiography and its manufacturing method and an X-ray detector, wherein the surface of the scintillator facing the X-ray is covered with photonic crystals of a two-dimensional or three-dimensional spatial structure capable of reflecting the visible light facing the photonic crystals generated by the scintillator to increase the intensity of the output light of the scintillator by more than 100%, thus enhancing the image brightness and improving the image resolution, in addition to reducing to a certain extent the interference between pixels due to the ability of the photonic crystals to control the direction of the light being reflected, for example, by controlling the reflecting direction so as to be vertical to the surface of the scintillator, and the manufacturing method and material for the photonic crystals are low in cost without toxicity, enabling it to be used more widely.

  • Patent number: 8853584
    Abstract: Disclosed herein is the use of differences in x-ray linear absorption coefficients to process ore and remove elements with higher atomic number from elements with lower atomic numbers. Use of this dry method at the mine reduces pollution and transportation costs. One example of said invention is the ejection of inclusions with sulfur, silicates, mercury, arsenic and radioactive elements from coal. This reduces the amount and toxicity of coal ash. It also reduces air emissions and the energy required to clean stack gases from coal combustion. Removal of said ejected elements improves thermal efficiency and reduces the pollution and carbon footprint for electrical production.
