Siemens has i identified the following issues with the artis q and artis q zen systems:1. in certain circumstances the release of radiation is blocked in connection with an error with the large display, for example, where an image cannot be displayed on the large display. in rare cases the system misinterprets the status of the large display and blocks the release of radiation.2. in the case of installations configured with a hospital emergency power supply for the entire system, radiation release may be blocked due to a software error, because a non-existent emergency power situation is detected by mistake.3. the coupling of failures caused by an electronic control element might lead to a radiation abort.

Siemens is providing a software patch to correct this issue. The software limits the blockage of radiation release to three seconds and the screen in the control room displays the message "No Xray, try again". After the next attempt, radiation can then be released without restriction. The software modification also prevents misinterpretation of the emergency power supply issue. An additional hardware signal supression component will be fitted to mitigate electronic control element failure. This action has been closed-out on 01/03/2016.
