System Operating Environment and EMC
Recently, the EMC (electromagnetic compatibility) problem in hospitals has drawn attention. To
prevent the problem from occurring and to ensure that the system operates in a stable manner,
this system conforms to IEC60601-1-2, the international standards regarding EMC.
The standards specify the requirements taking into account the following points:
<1> Adverse effect on other systems due to noise generated by this system
<2> Adverse effect on this system due to noise generated by other systems
<3> Adverse effect on this system due to static electricity
In actual hospitals, not all systems meet the standards.
Systems such as laser surgical unit, microwave accelerator, microwave thermal therapy system,
etc. emit high-level electromagnetic waves due to their characteristics. This system may adversely
affect ultrasound systems which use faint signals.
With regard to static electricity, the level may easily exceed the level specified in the standards
depending on the operating environment.
Therefore, take extreme care when determining the installation location.
For example, the system should be installed at a location as far from equipment emitting strong
electromagnetic waves as possible.
There are methods for reducing mutual influence to preventive the EMC problem. Refer to
subsection A.1 "HANDLING EMC" of the appendix.
