BACKGROUND Magnetic induction tomography (MIT) is a tomographic imaging technique, which has potential applications in security, industry, and medicine. Typically, sensors form a closed structure around the object. However, the measurement cannot be achieved using a closed sensor array in the process of severe brain trauma nursing and the neurosurgery operation. RESULTS The new sector sensor array magnetic induction tomography (SMIT) system is developed to realize real-time monitoring in the treatment of the brain. The functions of the drive coil and the sensor coil are separated in this system. The detection sensitivity of the imaging region boundary is analyzed through simulation. The sensor array locates on the high detection-sensitivity area, and the low sensitivity detection area is reserved for operation and clinical equipment. The sensor array received the energy of the signal accounts for reach 90% of the total energy. The integrity measuring data are obtained using a rotating scan in the system. In the experiment, we analyze the effects that system parameters have on the quality of imaging, for example, the scan step size, the number of sensors, the coverage angle of the sensor array and the scan angle. The experiment result provides a reference for the SMIT system design under a particular condition. In the complete measurement, the SMIT system reconstructs the images of center goal and margin goal, and the actual images have high peak signal-to-noise ratio. CONCLUSIONS The SMIT system can rebuild the conductivity distribution of the imaging region using incomplete space. In rotation measurement, the system provides a working place for clinical care. The flexible design of the system based on the experiment result makes the different treatment for brain injury own matched SMIT equipment.

磁感应层析成像中用于高电导率材料成像的扇区传感器阵列技术。

背景技术磁感应层析成像（MIT）是一种层析成像技术，其在安全，工业和医学中具有潜在的应用。通常，传感器在物体周围形成封闭结构。但是，在严重的脑外伤护理和神经外科手术过程中，使用封闭的传感器阵列无法实现测量。结果开发了新的扇形传感器阵列磁感应断层扫描（SMIT）系统，以实现对脑部治疗的实时监控。在该系统中，驱动线圈和传感器线圈的功能是分开的。通过仿真分析了成像区域边界的检测灵敏度。传感器阵列位于高检测灵敏度区域上，低灵敏度检测区域预留给手术和临床设备使用。传感器阵列接收到的信号能量占总能量的90％。完整性测量数据是使用系统中的旋转扫描获得的。在实验中，我们分析了系统参数对成像质量的影响，例如，扫描步长，传感器数量，传感器阵列的覆盖角度和扫描角度。实验结果为特定条件下的SMIT系统设计提供了参考。在完整的测量中，SMIT系统重建了中心目标和余量目标的图像，并且实际图像具有很高的峰值信噪比。结论SMIT系统可以使用不完整的空间重建成像区域的电导率分布。在旋转测量中，该系统为临床护理提供了工作场所。
