Abstract
An x-ray imaging system and method for providing three-dimensional data representing the contents of an object. An x-ray source and x-ray screen are used to acquire multiple x-ray images of the object from different perspectives. The different perspectives are obtained by placing the x-ray source at one end of a moveable arm. These images are processed by back-projecting each perspective image at known distances between the object and the x-ray source, and superimposing the back-projected images at each distance, thereby providing a set of image slices of the object along the z-axis.
