What does CBCT stand for?

Explanation:
CBCT stands for Cone Beam Computed Tomography. In dental imaging, this modality uses a cone-shaped X-ray beam and a flat-panel detector to rotate around the patient and collect data that are reconstructed into a 3D volume. The term combines the cone beam geometry with the reconstruction process that creates cross-sectional, three-dimensional images—similar in concept to CT but optimized for dental applications, often with lower dose and a focused field of view. This is the standard designation used in the field, which is why it’s the best choice. The other options describe the imaging in ways that aren’t the conventional terminology: Cone Beam Tomography omits “Computed,” Three-Dimensional Cone Beam Imaging describes the capability but isn’t the official name, and Computed Tomography With Cone Beam flips the order and adds wording not used in the standard acronym.
