Accuracy and reliability of stitched cone-beam computed tomography images
PURPOSE This study was performed to evaluate the linear distance accuracy and reliability of stitched small field of view (FOV) cone-beam computed tomography (CBCT) reconstructed images for the fabrication of implant surgical guides. MATERIALS AND METHODS Three gutta percha points were fixed on the inferior border of a cadaveric mandible to serve as control reference points. Ten additional gu...
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 کاملAccuracy of reconstructed images from cone-beam computed tomography scans.
INTRODUCTION The aim of this study was to determine whether 2-dimensional (2D) images produced from cone-beam computed tomography (CBCT) images taken with an iCAT scanner (Imaging Sciences International, Hatfield, Pa) can substitute for traditional cephalograms. METHODS Lateral and frontal cephalograms were taken of a radiographic phantom with known dimensions. Landmarks on the 2D images were...
متن کاملVolumetric accuracy of cone-beam computed tomography
PURPOSE This study was performed to investigate the influence of object shape and distance from the center of the image on the volumetric accuracy of cone-beam computed tomography (CBCT) scans, according to different parameters of tube voltage and current. MATERIALS AND METHODS Four geometric objects (cylinder, cube, pyramid, and hexagon) with predefined dimensions were fabricated. The object...
متن کاملEffect of Slice Thickness on the Accuracy of Linear Measurements Made on Cone Beam Computed Tomography Images (InVitro
Objective: Cone beam computed tomography (CBCT) is applied for the imaging of the maxillofacial and dental structures, particularly for surgical treatments and dental implants. The aim of this study was to assess the effect of slice thickness on the accuracy of CBCT linear measurements. Methods: In this diagnostic accuracy study, forty-two titanium pins with the same dimensions were inserted...
