Artis Icono Ceiling systems are equipped with an automatic collision detection at locations where collisions with users or equipment might occur. If the issue occurs, the collision sensor around the x-ray tube housing shows the following unintended behavior: when the Artis Icono Ceiling system was switched off for a longer time (e.g. overnight) and switched on, this collision sensor is falsely signaling non-existing collisions for up to half an hour.
