Chapter 2. Safety 2 – 17
A medical device can either generate or receive electromagnetic interference. The EMC
standards describe tests for both emitted and received interference.
Samsung Medison’s ultrasound products do not generate electromagnetic interference in
excess of standard levels established for such devices.
An Ultrasound System is designed to receive signals at radio frequency and is therefore
susceptible to interference generated by RF energy sources. Examples of other sources of
interference are medical devices, information technology products, and radio and television
transmission towers. Tracing the source of radiated interference can be a difficult task.
Customers should consider the following in an attempt to locate the source:
• Is the interference intermittent or constant?
• Does the interference show up only with one transducer operating at the same frequency or
with several transducers?
• Do two different transducers 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?
The answers to these questions will help determine if the problem resides with the system or the
scanning environment. After you answer the questions, contact the Samsung Medison
Customer Support Department.
