Determination of appropriate energy threshold range for accurate estimation of effective atomic number considering statistical uncertainty in photon‐counting techniques

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose The energy threshold is an important parameter for precise material identification employing photon‐counting techniques. However, in such applications, the appropriate energy threshold has not been clarified. Therefore, we aimed to determine the appropriate energy threshold range for precise material identification, focusing on ...
