Introduction: Metal-supported porcelain crowns (MSPC) and bridge restorations may be present in the mouths of patients undergoing CBCT imaging. Artifacts that are caused by these MSPCs may adversely affect image quality. The aim of this study is to determine the effect of different FOV (field of view) and localization in FOV on metal artifacts caused by MSPC. Methods:</...

leather artifacts have organic and degradable structure and some historic samples have remained from different historical periods. studies of these scarce specimens have a great importance in the conservation procedure by which the structural study of leather artifact for understanding production process and used materials can be achieved. for this purpose a historic leather bottle has been stu...

Introduction: Nowadays, Imaging of the myocardial perfusion (MPI) using the single photon emission tomography (SPET) in the diagnosis of coronary artery disease, especially myocardial ischemia, is of great importance. In contrast to the coronary artery angiography, MPI is non-invasive, less expensive and more physiological. Unfortunately, this image is affected by the some artifacts. Thes...

The relationship between the Tibetan prelate Tāranātha (1575-1634) and his major patrons, the various sDe pa of gTsang is a most complex one.
