Deep learning methods for virtual monoenergetic imaging from spectral CT
, 2023 Spectral photon counting computed tomography (CT) is a X-ray imaging modality that acquires energy-resolved data thanks to photon counting detectors that sort photons depending on their energy. This allows to decompose the object into its material constituents or to reconstruct virtual monoenergetic images.

Dual energy computed tomography virtual monoenergetic imaging: technique and clinical applications. [PDF]
Br J Radiol, 2019 Dual energy CT (DECT) has evolved into a commonly applied imaging technique in clinical routine due to its unique post-processing opportunities for improved evaluation of all body areas. Reconstruction of virtual monoenergetic imaging (VMI) series has shown beneficial effects for both non-contrast and contrast-enhanced DECT due to the flexibility to ...

Noise reduction in dual-energy computed tomography virtual monoenergetic imaging. [PDF]
J Appl Clin Med Phys, 2019 AbstractPurposeVirtual monoenergetic images (VMIs) derived from dual‐energy computed tomography (DECT) have been explored for several clinical applications in recent years. However, VMIs at low and high keVs have high levels of noise. The aim of this study was to reduce image noise in VMIs by using a two‐step noise reduction technique.MethodsVMI was ...
