Spectral, Photon Counting Computed Tomography : Technology and Applications Hardback

Spectral, Photon Counting Computed Tomography is a comprehensive cover of the latest developments in the most prevalent imaging modality (x-ray computed tomography (CT)) in its latest incarnation: Spectral, Dual-Energy, and Photon Counting CT.

Disadvantages of the conventional single-energy technique used by CT technology are that different materials cannot be distinguished and that the noise is larger.

To address these problems, a novel spectral CT concept has been proposed.

Spectral Dual-Energy CT (DE-CT) acquires two sets of spectral data, and Spectral Photon Counting CT (PC-CT) detects energy of x-ray photons to reveal additional material information of objects by using novel energy-sensitive, photon-counting detectors.

The K-edge imaging may be a gateway for functional or molecular CT.

The book covers detectors and electronics, image reconstruction methods, image quality assessments, a simulation tool, nanoparticle contrast agents, and clinical applications for spectral CT.
