Measurement of Temperature Distribution Using the Current Injection MRI

Abstract

A new temperature distribution measurement method using the current injection MRI is proposed. Since electrical impedance of biological tissues is very sensitive to their temperature, formation of current density inside the tissues is strongly dependent on the temperature distribution inside the tissues when external current is applied to the tissues during the current injection MRI. Therefore, the phase change at the image domain has correlations with the temperature change inside the tissues. Both simulation and experimental results have shown that a small change of temperature distribution can be measured using the current injection MRI.
