The user interface (UI) is one of the most critical components of an ultrasound machine and typically includes a touch panel with multiple buttons, TGC slide potentiometer and encoders. The UI is one of the most common parts to fail on an ultrasound system typically due to wear and tear of the mechanical encoders, tactile switches and/or elastomer membranes.
The UI or control panel is the gateway for interaction between the sonographer and the ultrasound system. If the control panel is not working, the system will not be fully functional for the user. It is critical to make sure that the UI is working to maximize uptime. I recommend a thorough visual inspection of the user interface looking for cracks in the bezel, missing knobs or any gel on the UI when performing a system preventive maintenance. Look for anything that might affect its performance.
The basic functionality of the control panel can be tested to ensure it is working correctly. This can typically be done through diagnostics – if you have access. The control panel can also be tested in imaging by pressing the buttons and turning the encoders to ensure they respond. If it is determined that the user interface is defective, I recommend that it be replaced with a compatible replacement which can be found by looking in the ultrasound field service manual. There is typically a sticker on the back of the user interface itself. It is important to ensure the compatibility of the replacement part by verifying it with the service manual.
