effect of exposure parameters on metal artifacts in cone beam computed tomography
objectives: the aim of this study was to assess the effect of tube current, kilovoltage peak (kvp), metal type, and the position of metal objects on metal artifacts in cone-beam computed tomography (cbct) images. materials and methods: titanium and cobalt-chromium rods were fabricated and placed in a dry human mandible. samples were scanned using a promax 3d cbct unit with different milli-amper...
متن کاملEvaluation of Metal Artifacts in Cone Beam Computed Tomography by Metal Supported Porcelain Crowns Using Different FOV and Localizations: An In Vitro Study
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:</...

Karin Andersson (2018): Metal Artifacts in Computed Tomography – impact of reduction methods on image quality and radiotherapy treatment planning. Örebro Studies in Medicine 172. Degradation of image quality by metal artifacts is a common problem in computed tomography (CT) imaging, which can limit the diagnostic value of a CT examination and also introduce inaccuracies in radiotherapy (RT) tre...
متن کاملAssessment of metal artifacts in three-dimensional dental surface models derived by cone-beam computed tomography
OBJECTIVE The aim of this study was to assess artifacts induced by metallic restorations in three-dimensional (3D) dental surface models derived by cone-beam computed tomography (CBCT). METHODS Fifteen specimens, each with four extracted human premolars and molars embedded in a plaster block, were scanned by CBCT before and after the cavitated second premolars were restored with dental amalga...
