Abstract: Advances in x-ray inspection technology have now made it possible to inspect components and assemblies with very small density variations. This includes hardware improvements like the new 16 bit digital detector technology. Digital detectors have been used in the medical industry to replace film for a few years now. Availability of this technology for industrial x-ray means industries like medical and defense will now benefit from the high quality, high reliability of this technology. This paper covers the technical aspects of the new detectors as compared to the existing detectors being used. It also discusses the inherent advantages for the engineers using x-ray inspection for various applications.

Once the availability of additional information is established, it is necessary to cover the new software tools that have now become available to take full advantage of this additional information. Advanced Defect Enhancement (ADE) filter is a sophisticated image enhancement tool for automatically adjusting the local contrast and brightness for each region of the X-ray image. It enhances low contrast structures across attenuation gradients due to different thickness or materials. In addition to its time saving, ADE results in higher inspection quality as defect visibility is substantially improved.
