1. A method of electrical impedance tomography, comprising the steps of:

  • injecting a current to a measurement target via at least one electrode pair selected from a plurality of electrodes attached to the measurement target;

    detecting voltage of a surface of the measurement target using a plurality of voltmeters connected to the electrodes that are not selected, respectively;

    adjusting gains of the voltmeters according to maximum values of the detected voltages, respectively;

    amplifying the detected voltages using the gain-adjusted voltmeters, respectively; and

    imaging an internal part of the measurement target based on the amplified voltages.
