1. A method for generating impedance images of the chest, comprising:

  • acquiring electrical data of the chest;

    obtaining electrocardiograph data of a patient;

    analyzing the electrocardiograph data to obtain information about breathing parameters at the time the electrical data was acquired; and

    reconstructing at least one impedance image of the chest from the electrical data and the information about breathing parameters;

    wherein the information about breathing parameters reduces the sensitivity of the at least one impedance image to breathing parameters.
