Photon‐counting normalized metal artifact reduction (NMAR) in diagnostic CT

Purpose Metal artifacts can drastically reduce the diagnostic value of computed tomography (CT) images. Even the state‐of‐the‐art algorithms cannot remove them completely. Photon‐counting CT inherently provides spectral information, similar to dual‐energy CT. Many applications, such as material decomposition, are not possible when metal artifacts are present. Our aim is to develop a prior‐based metal artifact reduction specifically for...
