摘要： An electroimpedance tomograph is provided with a plurality of electrodes (1), which can be placed on the body of a patient and are connected to a control and evaluating unit (20) via a selector switch (60). The control and evaluating unit (20) cooperates with the selector switch (60) such that two electrodes each are supplied with alternating current from an AC power source (22). The detected analog voltage signals of the other electrodes are sent into the control and evaluating unit (20) via a measuring amplifier (62) and AD converter (64) and are processed there in order to reconstruct the impedance distribution of the body in the plane of the electrodes therefrom. A symmetrical AC power source (22) is used to reduce common-mode signals. To make it possible to suppress errors due to common-mode signals, provisions are made for the control and evaluating unit (20) to be set up for making available an additional common-mode signal at an output during an adjusting mode of operation and to send it to the body via common-mode signal electrodes (4, 90) that can be placed on the body. The control and evaluating unit (20) is prepared, furthermore, to adjust the measuring amplifier (62) according to value and phase for each electrode pair connected by the selector switch (60) such that the common-mode signal at the output of the measuring amplifier (62) is minimized, and the adjusted parameters are stored for each electrode pair.

摘要： An electrode belt is provided for carrying out electrodiagnostic procedures on the human body. The electrode belt includes a belt (2), which is formed at least partially of an elastic material and surrounds the body of a test subject. A plurality of electrodes, are mechanically connected to the belt and are in flat contact with the body of the test subject. At least one contact passes from the electrodes through the belt (2) and is connected to a connection element (11), which is connected to a lead each of a multicore cable (6). Such an electrode belt offers marked advantages in terms of handling along with increased safety from movement artifacts.

摘要： An electroimpedance tomograph is provided with a plurality of electrodes placed on a body, measuring circuits that process the voltage signals recorded by the electrodes, and a control unit that supplies two, preferably adjacent electrodes each with an alternating current. The control unit has a preset feed frequency performed in different states and different preset feed frequencies performed at different frequencies. The control unit processes the processed voltage signals of all other electrodes to reconstruct the impedance distribution of the body in the electrode plane. To make the EIT more insensitive to electromagnetic interferences, the control unit provides for an automatic setting of the current feed frequency/frequencies to record a background frequency spectrum by detecting the electrode voltage signals over a preset period of time and record them as a voltage time series and transform them into a frequency spectrum. The control unit searches in the background frequency spectrum for a frequency (different states) or frequencies (different frequencies) that leads to a useful signal to background ratio above a preset threshold value when used as a feed frequency.
