  • 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.

  • Publication number: 20190346381
    Abstract: A scanning system for scanning an object, and a corresponding bracket and method are described. The system has a scanning chamber in which the object to be scanned is received. The system also has a displacement assembly which displaces the object along a displacement path passing at least partially through the scanning chamber. The system also includes a source for emitting electromagnetic (EM) radiation or X-rays against the object within the scanning chamber such that at least some of the EM radiation passes through the object. The source is angled relative to the displacement path at an angle in a range between about 5° to about 8° and about 22° to about 30°. Finally, the system may also have detectors arranged around the scanning chamber which detect the EM radiation which passes through the object. The system, bracket, and method allow for the production of representative three-dimensional views of the object.

  • Publication number: 20190346379
    Abstract: An x-ray screening system includes a plurality of x-ray screening devices each for scanning at least one object of interest. Each screening device emits x-rays which pass through the object of interest and which are detected by a group of detectors including at least one detector to provide measured x-ray energy signals. At least one central processor is in data communication with each screening device for receiving the measured x-ray energy signals from each screening device automatically and in real-time. The at least one processor automatically analyzes the measured x-ray energy signals in real-time to determine at least one property of the object of interest and determining whether the at least one property indicates that at least a portion of the object of interest is composed of a material of interest. The material of interest may be a potentially dangerous material.

  • Publication number: 20190219729
    Abstract: A method for assigning one of a safe and threat condition to an object includes determining density and effective atomic number values for a plurality of predetermined safe and threat objects, plotting the values in a probability map to correlate corresponding density and effective atomic number values with each of the safe and threat objects, scanning an object to provide dual-energy attenuation images representing the object, decomposing the attenuation images into dual-reference material equivalent path length images to provide reference material equivalent path lengths representing the object, converting the reference path lengths into object path lengths, determining the effective atomic number for each pixel representing the object, and, imposing the effective atomic number and the mass density of the unknown object onto the probability map to determine a probability that the object is correlated with one of the predetermined safe and threat objects.

  • Publication number: 20190212465
    Abstract: A method for assigning attributes to an unknown object includes the steps of scanning the unknown object at least partially overlapping with a background object within an x-ray scanning device to provide dual-energy attenuation images having dual-energy attenuation information representing an overlap region wherein the background object and the unknown object overlap, decomposing the attenuation images into reference material equivalent path length images, removing the background object to provide reference material equivalent path lengths representing the unknown object, converting the reference material equivalent path lengths representing the unknown object into unknown object path lengths multiplied by a predetermined scaling factor, reducing the scaling factor to provide a contour of the unknown object and unknown object path lengths, and, determining a density and effective atomic number of the unknown object.

  • Publication number: 20190213740
    Abstract: There is provided a method for assigning an attribute to an unknown object overlapping with a predetermined background object. The unknown object is scanned overlapping with the background object within an x-ray scanning device to obtain a plurality of dual-energy attenuation images having attenuation information representing the background object and an overlap region wherein the background object and the unknown object overlap. The dual-energy attenuation images are decomposed into reference material equivalent path length images. The reference material equivalent path lengths representing the background object in the overlap region are determined and eliminated from the overlap region to provide reference material equivalent path length images having first and second reference material equivalent path lengths through only the unknown object.

    Abstract: There is provided a method for assigning an attribute to x-ray attenuation including scanning in an x-ray scanning device first and second reference materials each having known atomic composition, dimensions and orientation in the scanning device. The device emits x-rays which pass through the first reference material with first reference material path lengths and the second reference material with second reference material path lengths. The x-rays are detected by detectors to provide a plurality of dual-energy attenuation images having dual-energy x-ray attenuation information. The dual-energy x-ray attenuation information in the dual-energy attenuation images is associated with the first and second reference material path lengths.

  • Patent number: 10254436
    Abstract: A scanning system, corresponding bracket and method are for scanning an object. The system has a frame defining a scanning chamber in which the object to be scanned is placed. The system also has a displacement assembly which displaces the object into and out of the scanning chamber. The system can also have a source which emits electromagnetic radiation or X-rays against the object within the scanning chamber such that the EM radiation passes through the object. The system can also have detectors arranged around the scanning chamber which detect the EM radiation which passes through the object. Each of the detectors forms a detector angle with a plane which can vary from one detector to the next. Similarly, the source can form an angle with the horizontal plane. The system, bracket, and method allow for the production of representative three-dimensional views of the object.

  • Publication number: 20180315396
    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.
