Spectral Photon Counting Computed Tomography

<p><em><strong>Spectral Photon Counting Computed Tomography</strong></em> 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.</p>
