Dual-energy information in computed tomography (CT) can be obtained through different
technical approaches. Most available scanner designs acquire scans at two different x-ray …

Objectives After endovascular aortic repair (EVAR), discrimination of endoleaks and intra-
aneurysmatic calcifications within the aneurysm often requires multiphase computed …

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 …

Photon-counting computed tomography (PCCT) is an emerging imaging technique that
enables multi-energy imaging with only a single scan acquisition. To enable multi-energy …

Background To assess the feasibility of dual-contrast spectral photon-counting computed
tomography (SPCCT) for liver imaging. Methods We present an SPCCT in-silico study for …

Aim To evaluate the noise characteristics of virtual monoenergetic images (VMI) obtained
from a recently introduced dual-layer detector-based spectral CT (SDCT), both in a phantom …

While model-based reconstruction methods have been successfully applied to flat-panel
cone-beam CT (FP-CBCT) systems, typical implementations ignore both spatial correlations …

This work evaluated the performance of a detector-based spectral CT system by obtaining
objective reference data, evaluating attenuation response of iodine and accuracy of iodine …
