肺癌的诊断和分期通常始于对可疑的外周胸部部位的评估。这种可疑的外周部位可以是孤立的肺结节或其他异常出现的感兴趣区域（ROI）。用于评估这种外围ROI的最新工艺涉及使用三维（M）多探测器计算机断层扫描（MDCT）胸部扫描的离线程序规划，随后使用经皮支气管镜进行支气管镜检查。我们提出了一个集成的基于计算机的系统规划外周支气管镜手术。该系统采用3D MDCT胸部图像作为输入，并自动执行几乎所有操作。医生需要的唯一交互是ROI位置的选择。该系统计算效率高，并顺利适应临床工作流程。系统中集成了一种新的曲面定义方法，该方法对于有效地进行周边场地的分析和规划至关重要。结果证明了该系统的有效性及其用于外周支气管镜检查的实时引导。爱思唯尔有限公司出版
The diagnosis and staging of lung cancer often begins with the assessment of a suspect peripheral chest site. Such suspicious peripheral sites may be solitary pulmonary nodules or other abnormally appearing regions of interest (ROIs). The state-of-the-art process for assessing such peripheral ROIs involves off-line procedure planning using a three-dimensional (M) multidetector computed tomography (MDCT) chest scan followed by bronchoscopy with an ultrathin bronchoscope. We present an integrated computer-based system for planning peripheral bronchoscopic procedures. The system takes a 3D MDCT chest image as input and performs nearly all operations automatically. The only interaction required by the physician is the selection of ROI locations. The system is computationally efficient and fits smoothly within the clinical work flow. Integrated into the system and described in detail in the paper is a new surface-definition method, which is vital for effective analysis and planning to peripheral sites. Results demonstrate the efficacy of the system and its usage for the live guidance of ultrathin bronchoscopy to the periphery. Published by Elsevier Ltd.
