<p>TheX-ray therapy appts. has a set of differing filters (10, 20..80) associated with different radiation voltages positioned next to one another in a filter holder (5). This has a sensor switch (12,22..82) for each filter (10,20..80) indicating whether or not the filter (10,20..80) is in position. The sensor switches (12,22..82) are coupled to the setting relays (11..81) for the radiation voltage so that this is regulated according to the filter (30) removed from the holder (5) and inserted in the tube. The latter has a further safety contact (9) only allowing the HV to be applied when the filter (30) is in position.</p> |
