Sensitivity distribution with target domain in magnetic induction tomography

Magnetic induction tomography (MIT) is a new reconstruction image technology with advantage of non-invasive, non-destructive and without contacting the target object directly, especially suitable for medical application. The low conductivity of the target object in medicine leads the low sensitivity of the target domain, which limit the signal measurement in experiment. This is one of the key problems that effect MIT applying to the actual measurement. On the basis of analyzing MIT eddy signal and interior sensitivity, the sensitivity distribution of four cases with target domain are carried out computation and analysis by modeling based on analogizing the structure of the brain. It proves that the sensitivity with target domain is different for different cases and the interior sensitivity under different measurement condition possess respective characteristic.
