Patent ID: 7486761

Claim:
A method comprising: providing an object scanning space having a center of rotation; providing at least a first source of X-rays; providing a first X-ray detector in a position to detect at least the X-rays that intersect the center of rotation; providing at least a second X-ray detector in a position to detect the X-rays that: do not overlap with the X-rays as are detected with the first X-ray detector; and detect at least the X-rays that intersect a periphery of a circle that circumscribes an outer extreme boundary of an object to be scanned in the object scanning space; wherein all of the X-ray detectors as are provided are insufficient to make a complete scan of the object scanning space without providing some relative motion as between the X-ray detectors and the object scanning space; further comprising providing a second source of X-rays wherein the first source of X-rays and the second source of X-rays are substantially opposite one another and wherein providing a first X-ray detector comprising disposing the first X-ray detector in a position that is opposite the first source of X-rays and providing a second X-ray detector comprises disposing the second X-ray detector in a position that is opposite the second source of X-rays.
