3D Analytic Cone-Beam Reconstruction for Multiaxial CT Acquisitions [PDF]

open access: yesInternational Journal of Biomedical Imaging, 2009
A conventional 3rd generation Computed Tomography (CT) system with a single circular source trajectory is limited in terms of longitudinal scan coverage since extending the scan coverage beyond 40 mm results in significant cone-beam artifacts.

A Hybrid Approach to Reduce Cone-Beam Artifacts for a Circular Orbit Cone-Beam CT System

open access: yesIEEE Access, 2018
In a cone-beam computed tomography (CT) system, the Feldkamp, Davis, and Kress (FDK) algorithm produces cone-beam artifacts due to insufficient object sampling in the missing cone region of frequency space.

Exact Interior Reconstruction with Cone-Beam CT [PDF]

open access: yesInternational Journal of Biomedical Imaging, 2007
Using the backprojection filtration (BPF) and filtered backprojection (FBP) approaches, respectively, we prove that with cone-beam CT the interior problem can be exactly solved by analytic continuation.

Motion binning in cone-beam CT without a prior Model [PDF]

open access: yes, 2010
Cone-beam CT (CBCT), used to reduce setup error in radiotherapy, takes a sequence of about 670 two-dimensional X-rays acquired in a circular arc around the patient over two minutes and reconstructs a three-dimensional volume from these projections ...

Cone beam CT in dental practice [PDF]

open access: yesBritish 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.

The success of cone beam CT [PDF]

open access: yesDentomaxillofacial Radiology, 2014
Today, 16 years after its introduction in Dentomaxillofacial Radiology (DMFR), cone beam CT (CBCT) clearly dominates the scientific literature on dentomaxillofacial (DMF) imaging. For some journals, a reader could get the idea that no other option for radiographic imaging exists.

Dental cone beam CT: An updated review [PDF]

open access: yesPhysica Medica, 2021
Cone beam computed tomography (CBCT) is a diverse 3D x-ray imaging technique that has gained significant popularity in dental radiology in the last two decades. CBCT overcomes the limitations of traditional two-dimensional dental imaging and enables accurate depiction of multiplanar details of maxillofacial bony structures and surrounding soft tissues.
