Abstract
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.
