Dynamic tomography
Web1. Introduction. Over recent years in X-ray computed tomography (CT), there has been a growing interest in dynamic and spectral CT thanks to the technological advancements on detector speed and sensitivity and on multichannel photon-counting detectors (PCDs), as depicted in the EPSRC Tomography roadmap [].In dynamic CT, the aim is to … WebDynamic myocardial computed tomography perfusion (DM-CTP) has good diagnostic accuracy for identifying myocardial ischemia as compared with both invasive and noninvasive reference standards. However, DM-CTP has not yet been implemented in the routine clinical examination of patients with suspected or known coronary artery disease. …
