Spectral, Photon Counting Computed Tomography 1st/2021

<p><em style="color: rgb(51, 51, 51); font-family: &quot;Amazon Ember&quot;, Arial, sans-serif;"><strong>Spectral, Photon Counting Computed Tomography</strong></em><span style="color: rgb(51, 51, 51); font-family: &quot;Amazon Ember&quot;, Arial, sans-serif;">&nbsp;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.</span>&nbsp;&nbsp;</p>
