The locating place of the sector sensor array (a) and the typical sensor array (b) in brain surgery. In the SMIT sensor array, the space between the drive coil and the sensor can be used as the operating area for doctors. The operating area is occupied only during the process of the scan. The repetitive installation of the sensor array can be avoided during surgery, in contrast to the classical MIT system. This feature can ensure the positioning accuracy of tomography
