Abstract:
1. An x-ray imaging system for providing three-dimensional data representing the contents of an object, comprising: an x-ray source; a moveable arm having a fixed end and a free end, the free end being attached to the x-ray source; an x-ray screen operable to detect x-ray images of the object when the object is placed between the x-ray source and the x-ray screen; wherein the arm is moveable to provide different positions of the x-ray source, thereby providing different perspective images to the x-ray screen; wherein the arm travels in a vertical arc in a plane parallel to the x-ray screen; wherein the x-ray source is moveable, at each position of the arm, to direct the x-ray aperture toward the center of the x-ray screen; a processing unit operable to receive a set of x-ray perspective images from the x-ray screen, each perspective image acquired from a different position of the x-ray source; and to apply a back projection algorithm to the set of x-ray perspective images, thereby providing a set of image slices of the object.
