The monitor receives the pulsated output signals from the dipole in different projections. As dipole, positive and negative electrodes are used, over which a DC voltage or a slowly alternating voltage is applied. On this voltage, short voltage pulses are superimposed as pulsated output signals from the dipole. The voltage selected is between 0 and 30 volts, and the dipole output signal uses voltages with pulses which deviate from the R-potential of an electrocardiogram. The monitor is located in separate positions around the dipole, pref. outside the body of the patient. - The position in which the electrode is inserted is one in which the conductivity condition or variation can be followed, being e.g. a centre in a pathalogical process. The pulsated output signal frequency, pulse width and/or amplitude are varied until the monitor receives a signal suitable for measurement. |
