1. Warnings
• Inspect the device thoroughly before use. Do not use the device if damaged.
• Check individual components on MR-safety when used together in a patient positioning system.
• Do not use MR unsafe items in an MR environment.
• Do not use the thermoplastic mask after its expiry date.
• The thermoplastic masks are for single patient use.
• Ensure that the mask is not too hot for skin contact before placing it on the patient.
• Do not remove the mask from the patient until the material cools completely. Removing the
thermoplastic mask before it has set may result in the mask’s deformation.
• If using more than one shim, do not exceed a thickness of 1.5 mm.
• In the USA, federal law restricts this device to sale by or on the order of a licensed healthcare
practitioner.
