Towards Achieving Quantitative Attenuation Values in CT with Energy-Integrated and Photon-Counting Detectors

Authors: Zijia Guo, Viktor Haase, Michael F. McNitt-Gray, Frederic Noo

Affiliation: Siemens Healthineers, University of Utah, David Geffen School of Medicine at UCLA

Abstract Preview: Purpose: The attenuation values in CT hold strong potential for disease diagnosis. However, they lack reliability, which has limited their use to clinical trials where variability can be controlled. S...
