An improved linear scan geometry laminography system that allows for generation of high speed and high resolution X-ray laminographs using an electronic detector operating in a time-domain integration mode coupled with a moving source of X-rays. In one embodiment, the improved scanning laminography system does not require any mechanical motion of the object being inspected, the X-ray source or detectors. Higher speed is achieved over conventional laminography systems due to the electronic nature of the scan. The same architecture also allows for both two-dimensional radiography and digital reconstruction techniques. Usage of the technique provides for higher throughput, higher resolution, and simpler designs than do currently available systems. An analysis of different system design parameters for the basic X-ray imaging architecture utilizing time-domain integration to generate cross-sectional images is included to facilitate specific design configurations. The relationships between resolution, speed, and cost are considered.
