Published in 2018 at "Journal of Applied Clinical Medical Physics"

DOI: 10.1002/acm2.12243

Abstract: Abstract The performance of a recently introduced spectral computed tomography system based on a dual‐layer detector has been investigated. A semi‐anthropomorphic abdomen phantom for CT performance evaluation was imaged on the dual‐layer spectral CT at… read more here.

Published in 2019 at "BMC Medical Imaging"

DOI: 10.1186/s12880-019-0367-8

Abstract: BackgroundDual-layer spectral detector CT (SDCT) may provide several theoretical advantages over pre-existing DECT approaches in terms of adjustment-free sampling number and dose modulation, beam hardening correction, and production spectral images by post-processing. In addition, by… read more here.

Published in 2022 at "Polish Journal of Radiology"

DOI: 10.5114/pjr.2022.123829

Abstract: Purpose Dual-layer spectral computed tomography (DLSCT) is a novel CT platform of dual-energy CT. Virtual non-contrast (VNC) imaging theoretically resembles true non-contrast (TNC) imaging by subtracting iodine attenuation from post-contrast data. We aimed to compare… read more here.
