Cephalometric measurements performed on CBCT and reconstructed lateral cephalograms: a cross-sectional study providing a quantitative approach of differences and bias

BMC Oral Health, 2022
Cephalometric analysis is traditionally performed on skull lateral teleradiographs for orthodontic diagnosis and treatment planning. However, the skull flattened over a 2D film presents projection distortions and superimpositions to various extents ...

Joint CT/CBCT deformable registration and CBCT enhancement for cancer radiotherapy [PDF]

Medical Image Analysis, 2013
This paper details an algorithm to simultaneously perform registration of computed tomography (CT) and cone-beam computed (CBCT) images, and image enhancement of CBCT. The algorithm employs a viscous fluid model which naturally incorporates two components: a similarity measure for registration and an intensity correction term for image enhancement ...

Assessment of the usefulness of morphometric and volumetric analysis of mastoid process for gender determination in forensic odontology: A retrospective cone beam computed tomographic study

Journal of Indian Academy of Oral Medicine and Radiology, 2022
Background: Personal identification is crucial in natural mass disasters and in man-made disasters when the body is highly mutilated and fragmented. The mastoid process of the skull is important in this regard for sex determination, since it is one of ...

CBCT-based Synthetic CT Generation using Deep-attention CycleGAN for Pancreatic Adaptive Radiotherapy.

Medical Physics (Lancaster), 2020
PURPOSE Current clinical application of CBCT is limited to patient setup. Imaging artifacts and Hounsfield unit (HU) inaccuracy make the process of CBCT-based adaptive planning presently impractical.
