As CBCT is widely used in dental and maxillofacial imaging, it is important for users as well as referring practitioners to understand the basic concepts of this imaging modality. This review covers the technical aspects of each part of the CBCT imaging chain. First, an overview is given of the hardware of a CBCT device. The principles of cone beam image acquisition and image reconstruction are described. Optimization of imaging protocols in CBCT is briefly discussed. Finally, basic and advanced visualization methods are illustrated. Certain topics in these review are applicable to all types of radiographic imaging (e.g. the principle and properties of an X-ray tube), others are specific for dental CBCT imaging (e.g. advanced visualization techniques).
由于锥形束计算机断层扫描(CBCT)在口腔颌面成像中被广泛应用,对于使用者以及转诊医生而言,理解这种成像方式的基本概念非常重要。本综述涵盖了CBCT成像链各部分的技术层面。首先,对CBCT设备的硬件进行概述。描述了锥形束图像采集和图像重建的原理。简要讨论了CBCT成像协议的优化。最后,阐述了基本和高级的可视化方法。本综述中的某些主题适用于所有类型的放射成像(如X射线管的原理和特性),其他主题则是牙科CBCT成像所特有的(如高级可视化技术)。
