一种用于体内微型诊疗装置定位的磁场检测电路设计
Design of a magneticfield detection circuit to locate the micro medical device inside the human body
【摘要】 空间磁场检测是磁场空间定位技术中的重要组成部分。根据将永磁体用于生物体内微型诊疗装置定位的实验研究需要,作者设计了一种基于单片机控制、能同时检测永磁体周围空间多点磁场参数的硬件电路。实验表明,本电路可以实现对永磁体空间磁场变化的实时检测,电路简单可靠,通道一致性好。
【Abstract】 The magnetic field detection is an important part of magneticfield-based position method.According to the need of experiment research for determining the location of micro device inside the human body through permanent magnet,this paper introduces a circuit based on S CM that is able to detect the multiposition magnetic parameters about the perma nent magnet at the same time.It is proved by experiments that the real-time d etection of the change of magnetic field can be realized through the simple and reliable circuit,which has good channel consistency.
