Device Standards
CAUTION
If the system is connected to other customer-supplied equipment, such as a local
area network (LAN) or a remote printer, Philips cannot guarantee that the
remote equipment will work correctly in the presence of electromagnetic phe-
nomena.
Although most remote devices will likely comply with their applicable standards
for immunity, those device requirements may not be as stringent as those
required for medical equipment. It is the responsibility of the installer and user of
this remote customer-supplied equipment to ensure that it functions properly in
the electromagnetic environment where the system is installed. For this reason,
Philips does not provide a list of compatible accessories. Philips suggests that the
installer or user of such a system consult with experts in the field of electromag-
netic compatibility and safety for guidance to ensure the safe and effective use of
the created system.
Electromagnetic interference may appear in many ways on the ultrasound system
and depends on the mode the equipment is operating in, the imaging control set-
tings, the type of transducer being used, the type of electromagnetic phenomena,
and the intensity level of the phenomena.
NOTE
Electromagnetic phenomena are not always present and may be transitory in
nature. It may be extremely difficult to identify the source of the interference.
CAUTION
When interference is present or intermittent, use caution when continuing to use
the ultrasound system.
NOTE
Table 6-7 describes a few typical interferences seen in imaging systems. It is not
possible to describe all manifestations of interference because it depends on many
parameters of the transmitting device such as the type of modulation used by the
signal carrier, the source type, and the transmitted level. It is also possible for the
interference to degrade the imaging system’s performance and not be visible in
the image. If the diagnostic results are suspicious, other means should be used to
confirm the diagnosis.
