  • Patent number: 8053745
    Abstract: A device for circumscribing a target site with a beam. The target site is located within a target body. The path of the beam is varied rotationally so as to form a cone with an isocenter at the cone's apex. The isocenter is fixed on the approximate center of the target site. The target body is rotated about a vertical axis passing approximately through the center of the target site, and the rates of rotation of the beam path and body, respectively correspond so that the beam intersects an axis passing through the target site at an approximately constant angle.

  • Patent number: 7486761
    Abstract: A first X-ray detector (203) is positioned to detect at least the X-rays that intersect the center of rotation (201) for an object (205) with respect to an X-ray source (202). A second X-ray detector (207) is then positioned to detect X-rays that do not overlap with the X-rays as are detected by the first X-ray detector as well as X-rays (210) that intersect a periphery of a circle (209) that circumscribes an outer extreme boundary (208) of the object to be scanned.

  • Publication number: 20080219404
    Abstract: One directs an X-ray fan beam (202) towards a target (205). A first linear array of detectors (207) serve to detect X-ray fan beam scatter (401) as occurs when at least portions of the X-ray fan beam interact with the target. The resultant scatter-based target information is then used to form a two-dimensional view of the target.

    Abstract: A drill bit includes a body defining an axis and first and second cylindrical portions, a coupling adapted for connection with a rotary driver, and a depth stop adjustably secured to a first portion by a plurality of adjusting fasteners in a manner to limit penetration of the bit into a target surface. A method of drilling a hole into the surface includes locating a drilling machine fitted with a drill bit over a target location, compensating for wear on the bit by setting a depth stop to limit travel of the bit at the predetermined depth, drilling at the target location until the depth stop contacts a surface, where the primary cutting surface forms a portion of the hole defined by a first diameter and the secondary cutting surface forms a portion of the hole defined by a second diameter in a single step, and removing the drill bit from the hole.

  • Patent number: 4989225
    Abstract: A dynamic computed tomographic X-ray scanner concurrently translates and rotates an object as it passes through an X-ray field. This compound motion makes it unnecessary to perform sequential passes or to relocate X-ray equipment between passes to complete a scan. A conveyor may carry a series of closely spaced turntables to give greatly increased throughput; and coordinated translation and rotation, whereby all objects give comparable images, permitting the images to be compared to find defective products. Preferred geometries greatly simplify the image reconstruction mathematics, particularly where the X-ray source is at the center of a circular object path.

  • Patent number: 4984257
    Abstract: A dynamic focusing device is provided for an X-ray scanner, the device comprising at least one detector module located in a position to receive, be illuminated by, and respond to X-rays. A source of X-rays is movable toward or away from the detector module. The module comprises a plurality of crystals each having a scintillation surface located in a common plane, with a plurality of septa separating the crystals. The septa have a height which is upstanding above the surfaces of the crystals far enough to reduce lateral X-ray scatter and to cast a shadow upon the surfaces of the crystals responsive to an illumination thereof from said X-ray source. The invention dynamically positions the detector module relative to the distance between the detector module and the source of X-rays in order to reduce substantially to a minimum any shadow in the X-rays cast by the septa upon the surfaces of the crystals.

  • Patent number: 4733082
    Abstract: A method and apparatus for improving the operation of a gamma camera which employs a planar scintillation crystal having a circumferential edge in the form of a mechanism and related method for cooling the crystal by thermally coupling the circumferential edge of the crystal to a heat sink and a mechanism and related method for applying pressure to the circumferential edge of the crystal sufficient to maintain the crystal in compression when cooled and thereby avoid cracking of the crystal due to temperature differentiation across the surface of the crystal.

  • Patent number: 4717962
    Abstract: A method for compressing and reconstructing original picture data representative of a plurality of pixels. The method includes a partitioning step and a weighting step. In the partitioning step, the original picture data is partitioned into a plurality of input blocks, with each such input block comprising data representative of border pixels shared with adjacent input blocks and unshared interior pixels surrounded by the border pixels. In the weighting step, data representative of the border pixels is weighted in order to reduce distortions of the original picture data caused by subsequent steps of such method.
