    Abstract: Provided is a highly reliable X-ray inspection device having two line sensors, in which accurate inspection results can be obtained even when there is displacement of the mounting position of the line sensors. The X-ray inspection device is provided with a conveyor unit for conveying an article, an X-ray emitter, a first line sensor, a second line sensor, a detection unit, and a corrected-image generation unit. The X-ray emitter emits X-rays to the article conveyed by the conveyor unit. The first line sensor detects, in a low energy band, X-rays that have passed through the article. The second line sensor detects, in a high energy band, X-rays that have passed through the article. The detection unit detects positional displacement of the second line sensor with respect to the first line sensor in horizontal direction and vertical direction.

    Abstract: A dual energy x-ray imaging system searches a moving automobile for concealed objects. Dual energy operation is achieved by operating an x-ray source at a constant potential of 100KV to 150KV, and alternately switching between two beam filters. The first filter is an atomic element having a high k-edge energy, such as platinum, gold, mercury, thallium, lead, bismuth, and thorium, thereby providing a low-energy spectrum. The second filter provides a high-energy spectrum through beam hardening. The low and high energy beams passing through the automobile are received by an x-ray detector. These detected signals are processed by a digital computer to create a steel suppressed image through logarithmic subtraction. The intensity of the x-ray beam is adjusted as the reciprocal of the measured automobile speed, thereby achieving a consistent radiation level regardless of the automobile motion. Accordingly, this invention provides images of organic objects concealed within moving automobiles without the detritus effects of overlying steel and automobile movement.

    Abstract: A method includes the steps of producing a first digital x-ray image of a part utilizing a full energy spectrum, producing a second digital x-ray image of the part with a hardened beam correlating to a higher energy portion of the full energy spectrum, subtracting the second x-ray image from the first x-ray image, and using a remainder of the subtracting step to locate the matter.
