Note
• If the device is interfered by power or signal cable, image quality
may be reduced or abnormally displayed. Such kind of interference
images could be easily identi ed and di erentiated from the physi-
ological characteristics of patient and longer clinical time consumed
but wouldn't have any diagnostic accuracy issue.
• If there is a certain frequency of image interference, there is a need
of isolation or ltering of the RF signal.
