Artifact 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 کاملPrevalence of Idiopathic Osteosclerosis on Cone Beam Computed Tomography Images
Objectives: This study was performed to investigate the prevalence of idiopathic osteosclerosis on cone beam computed tomography (CBCT) images of patients. Methods: In this descriptive, cross-sectional study, 240 CBCT scans of patients (125 women, 115 men) referred to a private oral and maxillofacial radiology clinic in Tehran in 2013 were selected and evaluated. Presence of idiopathic osteosc...

متن کاملMetal artifact reduction and image processing of cone-beam computed tomography data for mobile C-arm CT devices
A new method to reduce artifacts (MAR), produced by high-density objects, especially metal implants (MI), in X-ray CBCT is presented. MIs located in the field of view (FOV) result in artifacts influencing clinical diagnostics and treatments. The novel method reduces metal arti-facts by virtually replacing MIs by tissue objects of the same shape. This corrected data can be reconstructed with sig...
متن کاملEvaluation of neurovascular anatomical variations in maxillary anterior region in cone beam computed tomography images
Introduction: Incisive foramen in the maxilla is the oral terminus of the nasopalatine canal. This region is important in implantology, Therefore, the aim of this study was to investigate the neurovascular anatomical variations in the maxillary anterior region, observed on cone beam computed tomography (CBCT) images. Materials &Methods: In this cross-sectional study, maxillary CBCT ima...
