摘要:
A method for determining whether a probe for measuring the impedance of humanor animal body tissue has been placed over a boundary between different tissuetypes is described. The probe used in the method comprises at least a first (16),a second (22), a third (18) and a fourth (20) electrode arranged such that the third(18) and fourth (20) electrodes are each located substantially the same distancefrom both the first (16) and second (22) electrodes. The method comprises: drivinga current between the first (16) and the second (22) electrodes; measuring a firstvalue of an electrical parameter between the third (18) and the fourth (20) electrode;and determining whether the probe has been placed over a boundary between differenttissue types based on the first value. A probe for carrying out the method is alsodescribed.
