This invention describes a novel beam arrangement for multiview and dual view x-ray or radiation scanning systems used for inspection of objects. The method described herein is especially suited for scanning large objects such as palletized cargo or dense objects that are longer in one dimension, for example the height being larger than the width or depth. As the size and density of the object to be scanned increase, the absorption of the x-rays by the object increases with less of x-rays reaching the detectors. Therefore, in order to receive minimal signal for acceptable image quality, the scan speed is slowed which for certain objects it might become so low that it may not be acceptable. This invention describes a novel beam arrangement that greatly speeds up the scan speed. |
