Avoiding Electromagnetic Interference
An ultrasound system is designed to receive signals at radio frequencies, making them
susceptible to interference generated by RF energy sources. Other examples of interference
are medical equipment, information technology products, and radio and television
transmission towers.
To locate the source, investigate whether the problem resides with the system or the scanning
environment:
• Is the interference intermittent or constant?
• Does the interference show up only with one scanner or with several scanners?
• Do two different scanners operating at the same frequency have the same problem?
• Is the interference present if the system is moved to a different location in the facility?
• Can the EMC coupling path be attenuated? For example, placement of a scanner or printer
close to an ECG cable can increase electromagnetic interference. Moving the cable or
other medical equipment away from the location of the scanner or printer can result in
reduced electromagnetic interference.
If you find the interference's source, go to clarius.com/contact and contact Clarius.
