Apparatus and method for impedance measurement of body tissues |
摘要 |
An apparatus for impedance measurement of body tissue has a signal source which impresses an electrical signal in body tissue, circuitry for acquiring an impedance signal from the body tissue dependent on the impressed electrical signal, and an evaluation stage for evaluating the impedance signal by filtering higher frequency components and low frequency components from the impedance signal which correspond to the conductance of the tissue. A correction stage corrects the high frequency signal components with the low frequency signal components by eliminating the higher frequency signal components of influences due to changes in the tissue conductance. The corrected signal is supplied at an output of the correction stage.
