Cone beam computed tomography - know its secrets

Mohan Kumar et al. J Int Oral Health. 2015 Feb.

Abstract

Cone-beam computed tomography (CBCT) is an advanced imaging modality that has high clinical applications in the field of dentistry. CBCT proved to be a successful investigative modality that has been used for dental and maxillofacial imaging. Radiation exposure dose from CBCT is 10 times less than from conventional CT scans during maxillofacial exposure. Furthermore, CBCT is highly accurate and can provide a three-dimensional volumetric data in axial, sagittal and coronal planes. This article describes the basic technique, difference in CBCT from CT and main clinical applications of CBCT.

Keywords: Cone-beam computed tomography; X-ray; diagnostic imaging; spiral computed tomography.
