Introduction
In order to operate the MR system accurately and safely, the
operating personnel must have the necessary expertise as well as
knowledge of the complete operator manual. The operator manual
must be read carefully prior to using the MR system.
Layout of the operator manual
Your complete operator manual is split up into several volumes to
improve readability. Each of these individual operator manuals covers
a specific topic:
◾Hardware components (system, coils, etc.)
◾Software (measurement, evaluation, etc.)
Another element of the complete operator manual is the information
provided for the system owner of the MR system.
The extent of the respective operator manual depends on the system
configuration used and may vary.
All components of the complete operator manual may include
safety information that needs to be adhered to.
The operator manuals for hardware and software address the
authorized user. Basic knowledge in operating PCs and software is a
prerequisite.
The current operator manual
This operator manual is a supplement to the MR system operator
manual.

This manual may include descriptions covering standard as well as
optional hardware and software. Contact your Siemens Sales
Organization with respect to the hardware and software available for
your system. The description of an option does not infer a legal
requirement to provide it.
The graphics, figures, and medical images used in this operator
manual are examples only. The actual appearance and design of
these may be slightly different.
Male and female patients are referred to as “the patient” for the sake
of simplicity.

Safety
General safety information
All safety information of the valid operator manuals must be
adhered to without fail. It is merely supplemented by the notes
contained in this document.
MR scanning is not established for safe imaging of fetuses and
infants under two years of age. The responsible physician must
evaluate the benefits of the MR examination compared to those
of other imaging procedures.
Coils
CAUTION
Damaged RF coils/coil cables! Warming!
Patient burns
◆Never run coil cables over the patient's head.
◆Avoid direct contact between the coil cables and the patient.
◆Use only operationally satisfactory RF coils/coil cables.
◆In case of damage, contact Siemens Service.

Dangerous current loops may be generated if parts of the patient's
body touch. These loops may lead to burns or increase the probability
of stimulation. To avoid such loops, always use appropriate cushions
when positioning the patient. ( Page 75 Standard accessories)
Effect of antenna
Cables (e.g. from RF coils, ECG cables) that are run together and form
loops can act as receiver antennas and become very hot.
CAUTION
Arcing caused by coil cable loops!
Patient burns
◆Avoid coil cable loops.
RF coils that are not connected
To avoid electrical coupling between the RF coils and the Body coil,
the coils must be connected correctly.
WARNING
Coil cables/plugs not connected!
Patient burns
Irreparable damage to RF coil
◆Ensure that all RF coils used are connected.
◆Remove disconnected RF coils from the patient table.

Quality measurement
CAUTION
Deactivated RF transmitters (SAR) and gradient (dB/dt)
monitoring during quality measurement!
Injury to patient
◆Ensure that the patient is not located in the magnet bore.
Measurement phantoms
When measurement phantoms are used as intended within the scope
of quality assurance for RF coils, there is no physical contact with
measurement phantom fluids. The fluids are sealed inside the
measurement phantoms.
Risk due to aerosol formation
If phantom fluid has escaped, inhalable droplets (aerosols) containing
nickel may form in the event of a fire or atomization caused by strong
air currents. Carcinogenic effects cannot be ruled out if these aerosols
are absorbed by the body.
Handling and storing
WARNING
Improper handling of measurement phantoms!
Damage to measurement phantoms
Risk of fire due to lens effect
◆Store the phantoms at 20°C in a protected location.
◆Do not drop measurement phantoms.
◆Do not change measurement phantoms.
◆Do not store measurement phantoms in direct sunlight.

Phantom fluid spills
The measurement phantoms may contain either a nickel sulfate
solution or white oil (this liquid is blue in color).
The EC safety data sheets and legal regulations do not explicitly
mention possible hazards relating to phantom fluids.
Note the different measures to be applied for the various phantom
liquids. ( Page 18 First aid in case of contact with phantom fluid)
CAUTION
Contact with spilled phantom fluid (nickel sulfate)!
Personal injury
◆Wear protective clothing (gloves, work coat, and goggles).
◆Wear a mask with a filter for inorganic vapors if aerosols
(inhalable droplets) are formed.
◆Avoid skin contact with phantom fluids.
◆Do not use damaged phantoms.
◆Ensure that fluids from phantoms are disposed of properly.
1Put on protective clothing (goggles, overalls, and disposable
gloves).
2Absorb the fluid immediately using absorbent material such as
sand, sawdust, etc.
3Collect the fluid in a plastic bucket.
4Prevent phantom fluid from entering the waste water system.
5Change contaminated clothing.
6Clean your hands thoroughly using soap and water.
◆Always consult a physician immediately.

1Inform the fire department about the contents of the
measurement phantoms.
2Inform your local fire department that phantom fluids may produce
nickelous aerosols.
1Label the container accordingly.
2Hire an authorized special waste company for disposal.
3It is recommended that you contact the local Siemens Service
office as well as the environmental protection officer or the
