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 possible.
◆ 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 in the dialog window of the
syngo Acquisition Workplace. In the First Level Controlled Operating
Mode, medical supervision is mandatory.

Exposure to low frequency electromagnetic fields
During the measurement, patients are exposed to an electrical field
created by the time-varying magnetic fields of the gradient coils.
Assuming all other conditions remain constant, the strength of the
electrical field is directly proportional to the change of the magnetic
flux (dB/dt).
