CT实时引导下穿刺定位装置的研制

摘要

In this paper, a CT (Computerized Tomography)-guided puncture positioning device was introduced, which could move synchronously with the CT plate. During scan validation, it could be used to ifx the puncture needle and to repeatedly verify the real-time monitoring. With its one-time success rate being increased to more than 95%, the device had proven its highly improved accuracy in puncture.%本文介绍了一种CT实时引导下穿刺定位装置，主要由滑轨支架、三维云台、穿刺模块3部分组成，可随CT床板同步运动，CT扫描验证时可以固定穿刺针，反复实时验证监控。此装置可提高穿刺的精确度，一次性成功率高达95%以上。
