Print No. M4-08006G.623.01.02.02
 CAUTION
Incorrect positioning of the patient's head when using a head or
head/neck coil!
Wrong SAR calculation resulting in local overheating
◆ Always position the patient's head inside the head or head/
neck coil.
1 Use positioning aids and table pads to position the patient as
comfortably as possible on the patient table.
2 If the patient's hands or feet protrude over the table end, always
use the corresponding positioning aids.
3 Ensure the patient's feet do not hit the handle at the foot end of
the table or get caught in the gap between handle and table,
especially if the patient is very tall. Use positioning aids to position
the patient's feet a bit higher. When positioning the patient in the
prone position always use the foot roll and take special care when
the table moves out of the magnet.
4 If you are performing a triggered measurement: position the
patient in the supine position where possible.
5 When examining extremities, ensure correct patient orientation
and positioning.
Unlike examinations of the patient's torso, for which registration
of the image orientation data and positioning choices are limited,
imaging of the extremities is more freely selectable. Therefore,
registration of image orientation data when imaging extremities
may deviate from actual anatomical positioning of the patient.

Example: Positioning of the hand
◾ Right/left
◾ Palm/back of the hand
◾ Hand over the head
◾ Hand to the side along the body
