2-2-4 EMI limitations
Ultrasound systems are susceptible to Electromagnetic
Interference (EMI) from radio frequencies, magnetic fields, and
transients in the air or wiring. They also generate EMI. The
Ultrasound system complies with limits as stated on the EMC
label. However there is no guarantee that interference will not
occur in a particular installation.
Possible EMI sources should be identified before the Ultrasound
system is installed.
Electrical and electronic equipment may produce EMI
unintentionally as the result of a defect. Some of these sources
include:
• medical
lasers
• scanners
• cauterizing
guns
• computers
• monitors
• fans
• gel
warmers
• microwave
ovens
• light
dimmers
