[[File:Glossary Icon-2.png|100px|frameless|right|link=ICRP Glossary]]
A form of x-ray computed tomography in which the x rays in the form of a divergent cone or pyramid expose a two-dimensional detector array for image acquisition. It can also be referred to as ‘digital volume tomography’. Reconstruction is carried out using special algorithms.

In this publication the term ‘CBCT’ is used to designate a subset of computed tomography (CT) scanners that share certain key design features image quality characteristics and application domains that distinguish this set of scanners from multi-detector CT (MDCT) scanners. The most characteristic design feature that distinguishes CBCT scanners from MDCT scanners is the use of a two-dimensional digital flat-panel detector to yield a three-dimensional volumetric image in one rotation. Flat-panel detectors in CBCT allow wide cone angle large z-coverage and high spatial resolution at the expense of low-contrast resolution.
