X-Ray MegaVolt Digital Imaging Inspection System
Abstract
"Report developed under SBIR contract for topic A04-022." The X-ray Imaging Module (XIM) is a compact, efficient, inexpensive imager component that can be ganged with other XIMs to produce very high spatial resolution seamless images over very large areas, over 2 meters in a single dimension, if necessary. XIM provides fast, deep-dynamic range, low-noise calibrated digital readouts at a user- selectable/motion- coordinated rate, enabling virtually all reconstructive imaging applications, such as CT, TDI, and laminography at energies of 2 MeV. In phase 1, we built and tested a single prototype XIM unit at 2 MeV using the high energy x-ray source available at the Picatinny Arsenal. We proved a stitching approach that allows the construction of a single seamless very large image from multiple, smaller, slightly-overlapping images. We provided a multi-XIM unit that can image a region as large as 12 x 48 or 20 x 24 inches at high spatial resolution. A one-dimensional grid scatter- rejection scheme that will eventually reduce scattering at high energies was tested. In phase II, Skiametrics will build provide an erector-set multi-configuration 4-XIM unit, allowing very large areas, e.g., 12 x 48 inches or 20 x 24 inches, to be imaged at very high spatial resolution.
