SENSOR CONFIGURATION IN MAGNETOMETER FOR MEDICAL USE

A magnetometer system for medical use comprises one or more induction coils for detecting a time varying magnetic field. Each coil has a maximum outer diameter of 10 cm or less, and a configuration such that the ratio of the coil's length to its outer diameter is 0.9 or more, and the ratio of the coil's inner diameter to its outer diameter is 0.6 or more. Each induction coil comprises a magnetic core. The magnetometer system further comprises a detection circuit coupled to each coil and configured to convert a current or voltage generated in the coil by a time varying magnetic field to an output signal for use to analyze the time varying magnetic field. 一种用于医疗用途的磁力计系统包括用于检测时变磁场的一个或多个感应线圈。每一线圈具有10cm或更小的最大外径，并且具有配置，使得线圈的长度与其外径之比为0.9或更大，并且线圈的内径与其外径之比为0.6或更大。每一感应线圈包括磁芯。所述磁力计系统进一步包括检测电路，耦合到每一线圈，并且被配置为将通过时变磁场在线圈中生成的电流或电压转换为输出信号，用于分析该时变磁场。
