WARNING The ultrasound scanner is not designed to be used in potentially explosiv e
environments. It shou ld not be operated in the presence of fla mmable liquids or gases,
or in oxygen-enriched atmospheres.
There is a possible e xplosion hazard if the scanner is used in the presence of
flammable anesthetic. The scan ner should be placed at least 25cm (10 inches) from
the patient.
The ultrasound scanner contains a lithium battery. Never remove or replace this
battery. The lithium battery must not be removed except by a B-K Medical service
representative.
WARNING Do not plug the scanner into an ordinary power strip. If the ground
connection fails, this is dangerous because
•the total leakage current for all the conn ected equipment can exceed the limits
specified in EN/IEC60601-1 [2].
•the impedance of the ground connection will probably also exceed the limits
specified in EN/IEC 60601-1.
Leakage
current
Electrical
shock
ESD
WARNING When the equipment is used with 230V (and you believe the leakage
current would be within the UL limit if you were using 120V), power to the equipment
must come from an installation or supply unit with a center-tapp ed, 240V single-phase
circuit. This will make sure that chassis leakage current during single fault condition
fulfills the requirements specified in UL2601-1 [4] (limit of 300µA). If power is not
supplied in the way specified, the leakage current can be as high as 500µA, the limit
specified in EN/IEC60601-1. [2]
WARNING Never remove the cover to get access to the inside of the scanner. You
risk electrical shock if you do so. Do not allow anyone but qualified service personnel
to service the scanner.
WARNING Do not touch pins in connectors that have this symbol. Do not connect
anything to them unless you follow these ESD (electrostatic discharge) precautionary
procedures:
•Discharge your body to ground before you touch the pins with your hand or a tool.
For example, touch an unpainted metal part of the scanner cover.
•You can use a wrist strap connected to the additional protectiv e ground or potential
equalization terminal on the scanner if that is more convenient.
Anyone using the equipment should be taught to recognize the ESD symbol and to
take the necessary precautionary procedures.

Interference
Electrical Noise
Electrical

Other
equipment
nearby
WARNING Electrical noise from nearby devices such as electrosurgical devices – or
from devices that can tran smit electrical noise to the AC line – ma y cause disturbances
in ultrasound images. This could increase the risk during diagnostic or interventional
procedures.
Electromagnetic Interference
Medical electrical equipment requires special precautions regarding EMC
(electromagnetic compatibility). You must follow the instructions in this chapter
when you install the scanner and put it into service.
If the image is distorted, it may be necessary to position the scanner further from
sources of electromagnetic interference or to install magnetic shielding.
WARNING Do not use this equipment adjacent to oth er equipment . If you must place
it next to or stacked with other equipment, verify that it operates normally there and
neither causes nor is affected by electromagnetic interference.
EMC noise can reduce the usable image depth. Therefore, in order to avoid having
to repeat an ultrasound examination, you must make sure beforehand that the
ultrasound system can be used for the examination. Repeating an examination can be
regarded as a potential risk that should be avoided, especially if the examination
involves transducers used intracorporeally or transducers used for puncture.
RF (Radio Frequency) Interference
Portable and mobile RF (radio frequency) communication equipment can affect the
scanner, but the scanner will remain safe and meet essential performance
requirements.
An ultrasound scanner intentionally receives RF electromagnetic energy for the
purpose of its operation. The transducers are very sensitive to frequencies withi n
their signal frequency range (0.5MHz to 35MHz). Therefore RF equipment
operating in this frequency range can affect the ultrasound image. However, if
disturbances occur, they will appear as white lines in the ultrasound picture and
cannot be confused with physiological signals.
WARNING Other equipment may interfere with the scanner, even if that other
equipment complies with CISPR (International Special Committee on Radio
Interference) emission requirements.
WARNING If you use accessories, transducers or cables with the scanner, other than
those specified, increased emission or decreased immunity of the system may result.

WARNING To ensure safe performance, a qualified electrical engineer or hospital
safety personnel mu st v erify that the ultra sound scann er is correctly in stalled and that
it complies with the safety requirements described below:
•Use only the original power supply cord. This must be fitted with a hospitalapproved three-prong grounded power plug. See “P ower Supply Cord” on
page 331.
•The equipment must only be connected to a grounded AC power supply (or wall
outlet) that meets EN/IEC/NEC requirements or applicab le local regulatio ns. The
examination room’s grounding system should be checked regularly by a qualif ied
electronics engineer or hospital safety personnel.
•Never use ex tension cables. The increased length of the cable will increase the
resistance of the protective ground conductor beyond an acceptable level.
•Keep power supply cords, sockets and plugs clean and dry at all times.
WARNING Make sure that the power cord cannot be accidentally disconnected from
the wall or the scanner.

requirements
WARNING Always keep the exposure level (the acoustic output level and the
exposure time) as low as possible.
•
Scan patients only when clinical reasons make it necessary.
•
Keep exposure time as short as possible.
•
Be careful to prepare the patient correctly so that you get the best possible
image.
•
Start scanning at a low acoustic output level (see “Thermal and Mechanical
Indices” on page 28) and increase the level only as much as necessary to obtain
a satisfactory image.
•
If you switch from an application requiring high acoustic output levels (see
“Functions Affecting Acoustic Output” on page 29), to one that requires lower
levels (fetal scanning, for example), be sure to reset the levels before you scan.
(For example, start in B-mode.)
•
T ake into account all the types of tissue that may be affected. F or example, when
scanning a breast, it may be appropriate to monitor the TI in bone rather than in
soft tissue because the ribs will be subjected to ultrasound.
WARNING Before attempting to use B-K Medical equipment, y ou should be tr ained in
ultrasonography or be under the supervision of someone who is trained in
ultrasonography. You should also be thoroughly familiar with the safe operation of your
ultrasound system and should always use the transducer best suited to the
examination.
Acoustic output data for transducers used with the scanner are given on a CD
(BZ2100) that accompanies this user guide. The uncertainty level for each parameter
measured is listed in the user guide for each transducer. For definitions of the
parameters, refer to the Food and Drug Administration (FDA) Guide [7] as well as
EN 60601-2-37 [3] and AIUM/NEMA standards [8,9].
In North America, the FDA requires all ultrasound equipmen t to be cleared before it
is marketed in the United States.
The routes (or tracks) available for clearance by the FDA are well-defined. Track 3
is for diagnostic ultrasound systems that follow the Output Display Standard. Under
Track 3, acoustic output will not be evaluated on an application-specif ic basis, but
the maximum derated Spatial Peak–Temporal Average Intensity (I

As a rule of thumb, the Thermal Index (TI) indicates the highest expected
temperature increase in degrees Celsius. It is based on an average level of blood
perfusion. The displayed TI may underestimate the temperature rise in poorly
perfused tissues; you must take this into account when deciding on the maximum TI
you will allow. Conversely, in areas with a rich perfusion of blood the temperature
increase will be less than the displayed TI indicates.

Fever
A temperature increase of one degree Celsius increase in a patient with fever may
cause complications in certain circumstances; it may be safer to delay the
investigation.
Acoustic Output Measurement
All values are measured in water according to the EN and AIUM/NEMA display
standards [3, 8, 9]. For the some of the acoustic parameters, an estimated in situ
derated value is given. This is derived assuming a tissue attenuation of
0.3dB/cm·MHz when the estimated in situ derated value (I) is described by the

It should be stressed that the in situ values given are only applicable when there is

Possibility of Adverse Effects
Although it is believed that diagnostic ultrasound causes no significant biological
effects in mammalian tissue [3, 9], the user should be aware of the hypothetical
possibilities of adverse effects [10, 12, 13].
Current scientific and clinical concern over possible adverse effects is particularly
focused on fetal ultrasound scanning. It is due to the increased sensitivity of
mammalian cells and organs at this phase of their de velopment and the f act that such
a risk could have profound implications on public health. If you use high acoustic
output levels for some reason (see “Functions Affecting Acoustic Output”, below),
be sure to return to B-mode alone and turn down the power level before you do any
fetal scanning.
Functions Affecting Acoustic Output
The scanner has a control function that ensures that neither the I
value exceeds the maximum allowable value. When necessary, the scanner will
reduce the output voltage and/or PRF (pulse repetition frequency) to the transducer
in order to comply with requirements.
General and Safety I nformation
nor MI nor TI
SPTA
29
Some of the scanner functions can affect the acoustic output, as listed here.
(Instructions for using these functions are given in the relevant sections of this user
guide.)
•
Sizing functions such as ROI (region of interest) – in general, smaller size
results in higher acoustic intensity because the pulse repetition frequency (PRF)
is higher or the ultrasound beam is more strongly focused.
•
Focus – in general, strongly focusing the beam makes the acoustic intensity
higher.
Range – increasing the Doppler range increases the acoustic intensity by
increasing the PRF.
•
CFM Resolution – higher resolution increases the acoustic output.
•
Color box size – narrowing the color box generally increases the acoustic output
within it.
The user can set a Thermal Index limit. This will provide an upper limit for acoustic
output.
Default Acoustic Output
After the scanner has been turned off, the transducers will start in the default setup
when the scanner is turned on again. The default setup may be factory-defined or
defined by the user.
Fetal
scanning
References
The factory-defined default setup values of acoustic output for each transducer are
listed in the
General Transducer Information
(BB0555) manual.
These setups have been optimized to gi ve the best compromise between low acoustic
output and enough power to obtain the image features as quickly as possible. This is
part of the ALARA principle. The factory default setup for all transducers is B-Mode
to ensure the lowest acoustic output when you start scanning.
To change the default setup to another that satisfies the ALARA principle, see
Chapter 13, “Setting Up and Customizing Your System”.
When you enter a new patient ID, the transducer setup will be reset to the default
setup. You can prevent this from happening – see “Keeping Image Settings” on
page 40.
When you use transducers intended for fetal scanning, it is important to make sure
that the default settings are appropriate and to reset to the default setting before
scanning a new patient.
