Cone beam CT in dental practice [PDF]
British Dental Journal, 2009 Cone Beam Computed Tomography is a relatively new three-dimensional imaging technology, which has been specifically developed for imaging of the teeth and jaws. The aim of this paper is to acquaint the dental team with various forms of this technology and its potential applications.

Paired cycle-GAN based image correction for quantitative cone-beam CT.
Medical Physics (Lancaster), 2019 PURPOSE The incorporation of cone-beam CT (CBCT) has allowed for enhanced image-guided radiation therapy. While CBCT allows for daily 3D imaging, images suffer from severe artifacts, limiting the clinical potential of CBCT.
