The importance of cone-beam computed tomography in the diagnosis and orthodontic planning of impacted canine/ A importância da tomografia computada com cone-feixe no diagnóstico e planejamento ortodôntico de caninos impactos [PDF]
, 2019 Until recently, conventional radiographic methods were the only images used to help the planning of cases of patients with impacted teeth. However, they are two-dimensional images and provided limited information about the location and positioning of the

Neural Modulation Fields for Conditional Cone Beam Neural Tomography [PDF]
arXiv, 2023 Conventional Computed Tomography (CT) methods require large numbers of noise-free projections for accurate density reconstructions, limiting their applicability to the more complex class of Cone Beam Geometry CT (CBCT) reconstruction. Recently, deep learning methods have been proposed to overcome these limitations, with methods based on neural fields ...

Interpretations of Cone Beam Computed Tomography
Journal of the Medical Sciences, 2018 Dental volumetric tomography is the concept in which tissues of maxillofacial region are depicted using a cone beam shaped x-radiation to provide rapid accurate details. The salient advantages of cone beam computed tomography (CBCT) are shorter exposure time, reduced image distortion due to patient movements, decreased patient dose and multiplanar ...
