Material identification system
| DWPI Title: Method for identifying material in object, involves obtaining image of object, and identifying material in object by computer system by using estimated attenuations and known attenuation information for identifying material in object |
| Abstract: A method and apparatus for identifying a material in an object. An image of the object generated from energy passing through the object is obtained by a computer system. The computer system estimates attenuations for pixels in a sensor system from the image of the object to form estimated attenuations. The estimated attenuations represent a loss of the energy that occurs from the energy passing through the object. The computer system also identifies the material in the object using the estimated attenuations and known attenuation information for identifying the material in the object. |
| Use: Method for identifying a material in an object by using an object scanning system i.e. X-ray scanner for use in a medical field for visualizing a bone structure, and a dense tissue. Can also be used for a security purpose for scanning a luggage, a baggage, and containers in a commercial vehicle and a building, and for an industrial purpose for inspecting objects. |
| Advantage: The method enables measuring attenuation, and utilizing energy in the form of mono-energetic x-rays so as to accurately measure the attenuation of x-rays passing through an object and quickly and accurately identify the material in the object. |
| Novelty: The method involves obtaining an image of an object (106) generated from energy passing through the object by a computer system (134). Attenuations (136) for pixels (103) in a sensor system (110) are estimated from the image of the object to form estimated attenuations (138) by the computer system, where the estimated attenuations represent a loss of the energy that occurs from the energy passing through the object. Material (104) in the object is identified by the computer system by using the estimated attenuations and a known attenuation information (142) for identifying the material in the object. |
