  • Scanning-beam X-ray imaging system
    Patent number: 6649914
    Abstract: An x-ray imaging system according to the present invention comprising a stepped scanning-beam x-ray source and a multi-detector array. The output of the multi-detector array is input to an image reconstruction engine which combines the outputs of the multiple detectors over selected steps of the x-ray beam to generate an x-ray image of the object. A collimating element, preferably in the form of a perforated grid containing an array of apertures, interposed between the x-ray source and an object to be x-rayed. A maneuverable positioner incorporating an x-ray sensitive marker allowing the determination of the precise position coordinates of the maneuverable positioner.
    Type: Grant

  • Method and structure for generating a surface image of a three dimensional target
    Patent number: 5557113
    Abstract: A method and apparatus for generating a surface image of a target. The laser beam of a confocal laser microscope is moved along a scanning pattern on an area of a target. During each scanning pattern, the resulting electronic focus signal of the microscope is sampled at defined positions along the scanning pattern to generate a frame of pixel intensity values. At the end of each scanning pattern, the height of the target is slightly increased. A new frame of pixel intensity values is generated for each height of the target. The pixel intensity values of the frames are compared. The maximum pixel intensity value for each defined position along the scanning pattern is stored to create a single frame representative of the surface image of the target. In an alternate embodiment, the height at which each maximum pixel intensity value was measured is stored in a separate memory.
