支气管镜下胸中淋巴结活检是肺癌分期的重要步骤。在支气管镜检查之前，医生首先对患者的三维（3D）计算机断层扫描（CT）胸部扫描进行视觉评估，以确定可疑的淋巴结部位。接下来，在支气管镜检查时，医生将支气管镜引导到每个需要的淋巴结部位。不幸的是，在支气管镜检查过程中，医生没有将3D CT图像数据与实时视频流联系起来。因此，医生基本上必须盲目地进行活检，不同医生的技术水平差异很大。我们描述了一种能够在3D CT数据和支气管镜视频之间实现协同融合的方法。介绍了综合规划和制导系统以及内部ct -视频配准和融合方法。幻影、动物和人体研究说明了这些方法的有效性。Elsevier Ltd.出版。
Bronchoscopic biopsy of the central-chest lymph nodes is an important step for lung-cancer staging. Before bronchoscopy, the physician first visually assesses a patient's three-dimensional (3D) computed tomography (CT) chest scan to identify suspect lymph-node sites. Next, during bronchoscopy, the physician guides the bronchoscope to each desired lymph-node site. Unfortunately, the physician has no link between the 3D CT image data and the live video stream provided during bronchoscopy. Thus, the physician must essentially perform biopsy blindly, and the skill levels between different physicians differ greatly. We describe an approach that enables synergistic fusion between the 3D CT data and the bronchoscopic video. Both the integrated planning and guidance system and the internal CT-video registration and fusion methods are described. Phantom, animal, and human Studies illustrate the efficacy of the methods.
