System and method for determining physiological parameters based on electrical impedance measurements

摘要

A system and method for determining physiological parameters based on electrical impedance measurements is provided. One method includes obtaining electrical measurement signals acquired from a plurality of transducers coupled to a surface of an object and constructing a system matrix to define one or more relationships between the impedance measurement signals. The method also includes decomposing the system matrix to separate the electrical measurement signals.

1. A method for separating electrical measurement signals, the method comprising:
obtaining electrical measurement signals acquired from a plurality of transducers coupled to a surface of an object, wherein the plurality of transducers deliver electrical current continuously or in modulation such that excitations are applied across a temporal frequency range to the surface of the object to generate surface potentials and an electromagnetic (EM) field within the object; constructing a system matrix to define one or more relationships between the electrical measurement signals; and decomposing the system matrix to separate the electrical measurement signals.
