Abstract
A radiographic inspection apparatus for large containers, vehicles and structures having a movable frame which can straddle the container or object being inspected. The straddling frame has opposed parallel sides which carry a source of penetrating radiation and a detector array. The source or sources and detectors are moved along the length of a container while radiographic image data is being sequentially recorded. By summing or collecting the sequence of data over the length of a container as the straddling frame moves along, a full two-dimensional radiographic image of the container may be obtained. Radiographic images may be enhanced either by providing uniform motion for the straddling frame or by measuring non-uniform motion and compensating corresponding regions of the radiographic image.
