CAUTION
Stereotactic frames and similar devices: tips of screws may heat
up considerably, especially if MR examinations are performed in
the First Level Controlled Operating Mode!
Localized burns of the patient
◆ Please observe the recommendations and notes of the
manufacturer of the stereotactic frame.
◆ If the device consists of conductive material, only perform
measurements in the Normal Operating Mode.
◆ If you still need to switch to the First Level Controlled
Operating Mode, please observe the related safety notes.
To switch from the Normal Operating Mode to the First Level
Controlled Operating Mode, the user must explicitly select and
confirm the change. The request appears at the syngo Acquisition
Workplace. In the First Level Controlled Operating Mode, medical
supervision is mandatory.
SAR: Exposure to RF electromagnetic fields
During the course of an MR measurement, the patient’s body absorbs
energy from the RF field of the transmitter coil. Depending on the
type of transmitter coil used, the absorption is either concentrated
locally (when using so-called “Local RF Transmit Coils”) or relatively
uniform across the part of the body examined (when using volume
coils, for example, head, extremity, or body coil).
