Thin Film Magnetic Sensors for Ultrathin Bronchoscope Navigation

描述（由申请人提供）：Koronis Biomedical Technology Corporation（KBT）拟采用先进的薄膜磁传感器技术开发超薄支气管镜导航系统。半导体加工行业最近的技术创新使这一计划在技术上可以实现。使用先进的基于磁的定位技术来提供实时导航成像而无需荧光透视引导是非常期望的。超薄支气管镜中的这种定位系统允许操作者在肺的周边内导航并在活检工具接近周边病变时跟踪活检工具的路径。公共卫生相关性：申报项目涉及超薄支气管镜的导航。在美国，每年报告超过150，000个孤立性肺结节，其中每一个都可能表明肺癌的存在。支气管镜检查用于定位病人支气管的异常，必要时进行活检。全世界每年进行超过3，000，000次支气管镜检查。大多数肺部靶病变位于大型支气管镜无法到达的肺部外周区域。

DESCRIPTION (provided by applicant): Koronis Biomedical Technology Corporation (KBT) proposes to develop a navigation system for ultra-thin bronchoscopes using advanced thin-film magnetic sensor technology. Recent technological innovations in the semiconductor processing industry make this program technically achievable at this time. The use of advanced magnetic-based localization technology to provide real-time navigation imaging without fluoroscopic guidance is highly desirable. Such a localization system in an ultra-thin bronchoscope allows an operator to navigate within the periphery of the lung and track the path of a biopsy tool as it approaches a peripheral lesion. PUBLIC HEALTH RELEVANCE: The proposed project relates to the navigation of ultra-thin bronchoscopes. More than 150,000 solitary pulmonary nodules are reported annually in the US, each of which may indicate the presence of lung cancer. Bronchoscopy is used to locate anomalies in a patient's bronchus and if necessary, take a biopsy. Over 3,000,000 bronchoscopies are performed annually worldwide. The majority of target lung lesions are located in the peripheral areas of the lungs where large bronchoscopes cannot reach.
