This magnetic navigation system consists mainly of a powerful micro-magnetic transmitter, several magnetic sensors, a 16-Bit A/D converter, a data analyzer, a down-scan converter, and an image monitor. The magnetic transmitter is made of superior magnetic materials, and is 1.6mm in diameter x 10mm length. Our magnetic navigation system could identify the real location of the small magnet on the video monitor, and superimpose the real movements of the target on the display. In 2006, we used magnetic impedance sensors instead of microfluxgate sensors. So, the magnetic navigation system could detect and track a 2x2x10 mm sized magnetic transmitter in real-time within a 100x100x120 mm volume with an accuracy of 10 mm or less.In order to detect and track a small magnet embedded in the vicinity of a target tumor during surgery, we have developed a magnetic navigation system based on three-dimensional measurements with magnetic sensors. This idea is so unique that we have received Japanese patent No.4125449. For the touch panel device control system, we apply for a patent for new technology, as Japanese patent application 2006-166381, PCT/JP2007/062147.We succeeded in a partial resection of the pig lung including the target area with MI sensors.

该磁导航系统主要由一个强大的微磁发射器、几个磁传感器、一个16位a /D转换器、一个数据分析仪、一个下扫描转换器和一个图像监视器组成。磁性发射器由优质磁性材料制成，直径1.6mm ×长度10mm。我们的磁导航系统可以识别视频监视器上小磁铁的真实位置，并将目标的真实运动叠加在显示器上。2006年，我们使用磁阻传感器代替微磁通门传感器。因此，磁导航系统可以在100x100x120mm的体积内实时检测和跟踪2x2x10mm尺寸的磁发射器，精度为10mm或更小。为了在手术中检测和跟踪嵌入目标肿瘤附近的小磁铁，我们开发了一种基于磁性传感器三维测量的磁导航系统。这个想法是如此独特，我们已经获得了日本专利No.4125449。对于触摸屏设备控制系统，我们申请了新技术专利，如日本专利申请2006-166381，PCT/JP2007/062147。我们成功地用MI传感器切除了包括靶区在内的猪肺。
