CBCT
Pronunciation: see-bee-see-tee
Also written as: CBCT — Cone Beam Computed Tomography
Cone Beam Computed Tomography; a three-dimensional imaging modality used in oral and maxillofacial surgery to assess bone volume, anatomical structures, and pathology with lower radiation than medical CT.
Full Definition
Cone Beam Computed Tomography (CBCT) is a specialized X-ray imaging technique that produces three-dimensional volumetric data of the maxillofacial skeleton using a cone-shaped X-ray beam rotating around the patient. It provides high spatial resolution images of bone structures with significantly lower radiation exposure than conventional medical CT. In oral surgery documentation, CBCT is referenced in radiology reports, treatment-planning records, implant surgery notes, and third molar assessment reports. Editors should expand CBCT on first use in formal documents and distinguish it from CT (conventional computed tomography), which is a distinct imaging modality with a different scanner type and radiation profile.
Usage
Usage note: Expand on first use. Distinguish from conventional CT; do not use 'CBCT scan' as 'CT' already implies scanning — 'CBCT imaging' is preferred in formal writing.
