Cone beam computed tomography (CBCT) is a well-established imaging modality with numerous proven applications across multiple clinical disciplines. More recently, CBCT has emerged as an important imaging tool for bronchoscopists, primarily used during transbronchial biopsy of peripheral pulmonary lesions (PPLS). For this application CBCT has proved useful in navigating devices to a target lesion, in confirming device tool-in-lesion, as well as during tissue acquisition. In addition, CBCT is poised to play an important role in trials evaluating bronchoscopic ablation by helping to determine the location of the ablative probe relative to the target lesion. Before adopting this technology, it is key for bronchoscopists to learn some basic concepts that will allow them to have a safer and more successful experience with CBCT. Hence, in the current manuscript, we will focus on both technical and practical aspects of CBCT imaging, ranging from systems considerations, image quality, radiation dose and dose-reduction strategies, procedure room set-up, and best practices for CBCT image acquisition.
锥形束计算机断层扫描（CBCT）是一种成熟的成像方式，在多个临床学科中有众多已被证实的应用。最近，CBCT已成为支气管镜检查医师的重要成像工具，主要用于外周肺病变（PPLS）的经支气管活检。对于此应用，CBCT已证明在将设备导航至目标病变、确认设备进入病变以及组织采集过程中很有用。此外，CBCT在评估支气管镜消融的试验中，通过帮助确定消融探头相对于目标病变的位置，有望发挥重要作用。在采用这项技术之前，支气管镜检查医师了解一些基本概念至关重要，这将使他们在使用CBCT时获得更安全、更成功的体验。因此，在当前的手稿中，我们将专注于CBCT成像的技术和实际方面，包括系统考虑、图像质量、辐射剂量和剂量降低策略、手术室设置以及CBCT图像采集的最佳实践。
