Anaesthetic set-up for ultra-high-field anaesthesia, including an MR conditional Fabius MRI Dräger anaesthesia machine (Dräger, Lübeck, Germany) and Philips Invivo MR400 monitoring system (Philips, Amsterdam, The Netherlands) around a 7T Siemens Magnetom Terra scanner (Siemens AG, Munich, Germany). The black and yellow dashed lines represent where the MR conditional anaesthesia machine should be positioned. The black dashed line around the MRI scanner represents the 40 mT line.
