Simulation study on size and location identification of tumors in liver tissue through eddy current distribution analysis

In identifying the location of tumors in the liver, eddy current characteristics analysis can be applied since the conductivity value of normal tissue and tissue with tumors are different, which are 2.88 mS/cm and 5.33 mS/cm, respectively at 1 MHz. In this letter, simulation based on small scale magnetic induction system was carried out. The system consists of a 10 cm diameter sensor jig and a cone type screen excitation coil as the primary field source. Simulation results showed that eddy current analysis is capable of identifying location and size of tumors in a liver tissue phantom. This result may have an impact in Magnetic Induction Tomography (MIT) research since MIT imaging modality is based on electrical conductivity property of the material of interest.
