The Challenge Inequity in health care access is a major cause of increasing disease burden, catastrophic medical expenses, and inability to escape poverty, especially in the developing world [1–6]. Government programs to effect disease surveillance and treatment do exist, such as for tuberculosis, yet proper implementation is often lacking, especially in(More)
Radiation therapy (RT) is one of the modalities employed for treatment of cancer patients by irradiating the region to be treated using ionizing radiation. In radiation therapy, accurate patient positioning is an important requirement for precise dosage delivery. This paper presents a methodology for image registration employed in verification of the(More)
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)
