Material Identification Using Dual Energy X-ray Absorptiometry
[report]
2021
unpublished
Two implementations of dual energy X-ray absorptiometry were studied to identify materials using X-ray attenuation data taken with the Digital Radiography and Computed Tomography (DRCT) systems that were developed for the Recovered Chemical Materiel Directorate (RCMD). Maitrejean et al.'s approach utilizes eigen effects through Principal Component Analysis, while Osipov et al.'s approach proposed a physics-based method. Both approaches approximate mass attenuation coefficients of materials as a
