Dosimetry of Critical Organs in Maxillofacial Imaging with Cone-beam Computed Tomography
Background: While the benefits of cone-beam computed tomography (CBCT) are well known in maxillofacial imaging, the use of this modality is not risk-free.Objective: The aim of this study was to evaluate the exposure doses received by patients during maxillofacial imaging with CBCT.Methods: Entrance surface dose (ESD) was measured by using thermoluminescent dosimeters (TLDs) attached to the eyes...
متن کاملCorrelation Between Tissue Densities in Computed Tomography and Three Different Cone-Beam Computed Tomography Units (In Vitro)
Background and Aim: Bone density is of great assistance in the selection of the proper implant site. The present study aimed to assess the correlation between tissue densities in computed tomography (CT) and three different cone-beam computed tomography (CBCT) units. Materials and Methods: In this descriptive study, a radiographic phantom consisting of a transparent polymethyl methacrylate (PM...
متن کاملبررسی مقایسهای دو سیستم Cone Beam CT به لحاظ دقت اندازهگیری خطی محلهای قراردهی ایمپلنت در مندیبل بهصورت In Vitro
Background and Objective: There are critical areas in the mandible that should be considered during implant placement such as inferior alveolar canal, mental foramen, and the root of the adjacent tooth. Two-dimensional images obtained from periapical, panoramic, and conventional tomography are considered in the evaluation of implant placement and bone quality. Cone-beam computed tomography (CBC...
متن کاملArtifact reduction techniques in Cone Beam Computed Tomography (CBCT) imaging modality
Introduction: Cone beam computed tomography (CBCT) was introduced and became more common based on its low cost, fast image procedure rate and low radiation dose compared to CT. This imaging modality improved diagnostic and treatment-planning procedures by providing three-dimensional information with greatly reduced level of radiation dose compared to 2D dental imaging modalitie...
متن کاملEvaluation of the gray level in CBCT systems and its relationship with HU in CT Scanners
Introduction: Cone-beam CT (CBCT) is an imaging system which offers three-dimensional (3D), multiplanar images and has many advantages over computed tomography (CT) including shorter acquisition times for the resolution desired in dentistry, lower radiation dose to the patient, reasonable price and higher spatial resolution but CBCT scanners are unable to display actual Hounsf...
متن کاملEvaluation of Cone Beam Computed Tomography in Diagnosis and Treatment Plan of Impacted Maxillary Canines
Introduction: Maxillary canines have important roles in facial appearance, development of arch, and functional occlusion. Radiographs are important in evaluating the location and nature of these anomalies. The purpose of this study was to evaluate two types of 2D and 3D imaging technique in diagnosis and treatment of maxillary impacted canines. Methods: Thirty eight patients (50 impacted canine...
