  • Method for reconstructing the image of an object scanned with a laser imaging apparatus
    Patent number: 6130958
    Abstract: A method for reconstructing an image of a scanned object comprises the steps of collecting object data by scanning the object with a laser beam and detecting the light passing through the object; collecting perimeter data of the object during the scanning step; transforming the object data to parallel ray geometry; correcting the projection data using the perimeter data; and backprojecting the data in image space.

    Assignee: Imaging Diagnostic Systems, Inc.
    Inventors: David P. Rohler, Sastry L. A. Kasibhatla, Steven Ross
  • Apparatus and method for determining the perimeter of the surface of an object being scanned
    Patent number: 6044288
    Abstract: An apparatus for determining the perimeter of an object being scanned comprises a scanning chamber for receiving therein an object being scanned; a source of laser beam disposed within the scanning chamber for impinging on the object being scanned, the laser beam being adapted to orbit around the object; an array of sensors disposed within the chamber, each of the sensors being adapted to detect light emanating from the surface of the object due to the laser beam exiting from the object; and each of the sensors being disposed such that at least only one of the sensors generates a peak response to light emanating from a point on the surface at a predetermined distance from a reference point, such that at each angular position of the laser beam in the orbit, a specific point at a distance from the reference is determined, thereby to generate a set of points representing the perimeter of the surface after a complete orbit.

  • Device for determining the perimeter of the surface of an object being scanned and for limiting reflection from the object surface
    Patent number: 6029077
    Abstract: An apparatus for determining the perimeter of an object being scanned comprises a movable arm adapted to follow the surface of an object being scanned as the arm is orbited around the object; the arm having one end being adapted to maintain contact with the surface as the arm is orbited around the object; and an encoder operably connected to the arm for determining the movement of the lever arm at each angular position around the object. An opaque cup is positioned at one end of the lever arm immediately over a point on said surface at which a laser beam impinges on the surface of the object being scanned such that reflection from the surface is retained within the cup.
