Two-dimensional and three-dimensional cephalometry using cone beam computed tomography scans

, 2015
Lateral cephalometric radiograph produces a two-dimensional image with several drawbacks. Cone beam computed tomography (CBCT) allows obtaining a three-dimensional representation of the craniofacial structures and seems to overcome the problems of ...

Reproducibility of landmark identification on different CT images of the head in three-dimensional cephalometry [PDF]

, 2010
Cephalometry is the scientific measurement of the head and is a widely used technique in orthodontics and craniofacial surgery. In a previous study, a new method for three-dimensional computed tomography (3D CT) cephalometry was investigated, in which ...
