Imaging is a highly dependent technology in the clinical assessment of a patient. With respect to the dental field, imaging has travelled a long way from the conventional radiographs to modern techniques like the computed tomography (CT) and the cone-beam computed tomography (CBCT). This article describes the evolution made in the CT in the field of dental imaging and attempts to compare the CT...

PURPOSE To develop a projection quality-driven tube current modulation method in cone-beam computed tomography for image-guided radiotherapy based on the prior attenuation information obtained by the planning computed tomography and then evaluate its effect on a reduction in the imaging dose. MATERIALS AND METHODS The QCKV-1 phantom with different thicknesses (0-400 mm) of solid water upon it...

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 ...
