INTRODUCTION The objective of this study was to evaluate the effect of the orientation of cone-beam computed tomography (CBCT) images on the precision and reliability of 3-dimensional cephalometric landmark identification. METHODS Ten CBCT scans were used for manual landmark identification. Volume-rendered images were oriented by aligning the Frankfort(More)
PURPOSE To evaluate the accuracy of three-dimensional cephalometric measurements obtained through an automatic landmark detection algorithm compared to those obtained through manual identification. METHODS The study demonstrates a comparison of 51 cephalometric measurements (28 linear, 16 angles and 7 ratios) on 30 CBCT (cone beam computed tomography)(More)
PURPOSE Cone-beam computed tomography (CBCT) is now an established component for 3D evaluation and treatment planning of patients with severe malocclusion and craniofacial deformities. Precision landmark plotting on 3D images for cephalometric analysis requires considerable effort and time, notwithstanding the experience of landmark plotting, which raises a(More)
One of the major barriers for the social inclusion of blind persons is the limited access to graphics-based learning resources which are highly vision oriented. This paper presents a cost-effective tool which facilitates comprehension and creation of virtual directed graphs, such as flowcharts, using alternate modalities of audio and touch. It provides a(More)
