Abstract
Dual-energy subtraction (DES) imaging is well known to subtract materials of different atomic numbers (e.g. high Z and low Z values) and thus, enable material classification. Current approaches to DES imaging have trade-offs, such as motion artifacts, low sensitivity due to losses in a mid-filter, and a lack of portability. Recently, a portable triple-layer flat panel detector (FPD) was demonstrated for use in single-shot diagnostic medical DES imaging that could simultaneously provide improved sensitivity and removal of patient motion artifacts. In this work, we evaluate the feasibility of such a detector for portable NDT X-ray imaging. Various image quality metrics and practical images are provided.
