beam hardening artifacts by dental implants: comparison of cone‑beam and 64‑slice computed tomography scanners
background: cone beam computed tomography (cbct) is an alternative to a computed tomography (ct) scan, which is appropriate for a wide range of craniomaxillofacial indications. the long‑term use of metallic materials in dentistry means that artifacts caused by metallic restorations in the oral cavity should be taken into account when utilizing cbct and ct scanners. the aim of this study was to ...

متن کاملMulti-Material Beam Hardening Correction(MMBHC) in Computed Tomography
In computed tomography (CT), the nonlinear attenuation characteristics of polychromatic X-rays cause beam hardening artifacts in the reconstructed images. State-of-theart methods to correct the beam hardening effect are mostly single material precorrections (e.g. water-precorrection), which are far less efficient when more than one material is present in the field of measurement. The use of tho...
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...
