Abstract
The invention relates to an ionization chamber which includes a plurality of measuring field electrodes (,) which are arranged on a substrate (,) at a distance from one another and are provided with supply leads (,), and at least one electrode (,) which is arranged at a distance from and faces the substrate and emits charge carriers under the influence of X-rays. An insulating layer (,) provided on the supply leads and/or on the electrode, at least at the area of the supply leads, prevents the signals from the ionization chamber from being falsified by the charge carriers incident on the supply leads. The electrically insulating (layers) have such a high X-ray transparency that they are practically not reproduced in an X-ray image.
