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.
锥形束计算机断层扫描（CBCT）是一种先进的成像方式，在牙科领域具有很高的临床应用价值。CBCT已被证明是一种成功的检查方式，一直用于口腔颌面成像。在进行颌面扫描时，CBCT的辐射暴露剂量比传统CT扫描少10倍。此外，CBCT高度精确，能够在轴向、矢状面和冠状面提供三维容积数据。本文介绍了CBCT的基本技术、与CT的区别以及CBCT的主要临床应用。
