Noise
Ultrasound machines are susceptible to Electromagnetic Interference (EMI) from radio frequencies,
magnetic fields, and transients in the air or wiring. They also generate EMI. Possible EMI sources
should be identified before the unit 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
•
portable phones
The presence of a broadcast station or broadcast van may also cause interference.
When talking to the customer, try to gather as much information as possible about the conditions when
the noise appear:
