12.9 IMAGE HAS WAVY INTERFERENCE
To mitigate wavy interference on the ultrasound image, ensure:
• the Ultrasonix system is the only device connected to a dedicated wall outlet. (Sharing a wall outlet with other devices that
emit magnetic interference - such as an X-ray machine, computer server or halogen light - can cause noise on the power
line which interferes with the ultrasound image.)
• the copper fingers around the edge of the modulo have been depressed. In the event the copper fingers are no longer in
firm contact with the front block, gently lift them back into place to restore proper transducer grounding
• a medical grade power cable connects the system to a wall outlet in order reduce/eliminate interference from the power
line.
12.10 IMAGE HAS THREE (3) UNIFORM BLACK AREAS (LEFT, MIDDLE, RIGHT)
