摘要：
We present the design of a dual energy (DE) X-ray computed tomography (CT) test bench. It employs amorphous silicon (a-Si:H) imaging arrays and helical cone-beam geometry. Our goals are to evaluate: (1) the applicability of a-Si:H imaging arrays for tomography; (2) how our previously published dual energy penalized weighted least squares (DE PWLS) reconstruction method performs on experimentally acquired data; and (3) the optimal imaging geometry. This will allow us to design a setting that can be used clinically for attenuation correction for emission tomography, various quantitative computed tomography (QCT) applications, and removal of metal streak artifacts.
