20100290691 | EXAMINATION OF A REGION USING DUAL-ENERGY RADIATION - A first image including a projection of a portion is generated based on data representing attenuation of higher-energy radiation having a peak energy of at least 1 MeV that passes through a portion of an inspection volume. A second image including a projection of the portion is generated based on data representing attenuation of lower-energy radiation passing through the portion of the inspection volume. A dual-pixel image is created from the first image and the second image. A region of interest is selected from the dual-pixel image. A first basis function that is derived from an attenuation characteristic associated with the region of interest is selected. The region of interest is represented in terms of an amplitude associated with the first basis function and an amplitude associated with the second basis function. | 11-18-2010 |
20110189718 | Systems And Methods For Segregating Mixed Material Streams - The invention relates to methods and systems of detecting useful material in a mixed solid, liquid and/or gaseous material stream. The methods include defining a value range requirement for at least one parameter of interest of useful material to be selected from the material stream, passing the material stream through at least one detector adapted to measure the parameter of interest of the material stream, and separating the material stream into useful material and residue based on the measured parameter. The systems comprise at least one detector adapted to measure a parameter of interest of the material stream passing therethrough; and at least one separator for separating the material stream into useful material and residue based on the measured parameter after passing through the detector. The system may further comprise treaters, processors, and controllers. | 08-04-2011 |
