Cone Beam Computed Tomography (CBCT) is now widely available to dentists for examining hard tissues in the dental and maxillofacial regions. CBCT gives a three-dimensional view of anatomy and pathology. It uses a cone shaped source of ionizing radiation and a two-dimensional area detector fixed on a rotating gantry to acquire multiple sequential projection images in one complete scan around the area of interest. It is important, as an users to understand the basic concepts of this imaging modality. This review covers the basics of dental CBCT imaging including the hardware used, image acquisition, image reconstruction and image visualization.
