Abstract :
A novel algorithm for multienergy X-ray radiography systems that simultaneously estimate multiple measurements with energy diversity is presented. In contrast to conventional dual source X-ray radiography which utilizes simple weighted subtractions, the proposed algorithm aims for an accurate material decomposition of more than two materials. The numerical simulation as well as the real experiment using an energy discriminating detector confirmed our finding.
