中文摘要:
      目的:设计基于磁传感器扫描的多点磁目标检测系统,为实现人体内多个胶囊内镜的定位和纳米磁性药物的检测奠定基础。方法:利用三轴隧道效应磁阻传感器在磁源附近做圆周运动,获取多组磁信号后通过三维坐标变换,利用定位算法逆向求解出永磁体的位置。结果:通过编写LabVIEW上位机程序,实现对两个磁目标的轨迹示踪和运动曲线的存储与回放。结论:检测系统具有实时性好、精度高、成本低等优点,对人体内多个胶囊内镜的定位和纳米磁性药物的检测具有潜在应用价值。
英文摘要:
      Objective:A localization system for multiple magnetic targets based on magnetic sensor rotation detection was studied,which was aimed at realizing human multiple capsule endoscopy positioning and nano?magnetic drug testing. Methods:A three?axis tunneling magnetoresistive sensor was used to make a circular motion near the magnetic source. Three sets of magnetic signals were acquired and transferred by three?dimensional coordinates. The position of the permanent magnet was solved using a positioning algorithm. Results:Through the preparation of LabVIEW PC program,the trajectory of two magnetic target tracking and motion curve storage and playback were achieved. Conclusion:The detection system has the advantages of good real?time,high precision and low cost,it has the potential application value for the positioning of multiple capsules in the human body and the detection of nano?magnetic drugs.
