Even the most technologically advanced machines are prone to wear and breakdowns. Like any machine, they require routine maintenance and attention to ensure they perform their best. State-of-the-art machines, such as the GE Logiq E9, are only as good as the sum of their parts. If the probe malfunctions, it can affect the rest of the machine and provide skewed results. A damaged transducer probe can lead to a misdiagnosis and can be dangerous for both the patient and the sonographer. Here are some guidelines for ultrasound transducer troubleshooting to help you recognize the signs and keep your machine operating well.
How to Identify Image Dropouts
Black lines in the image area are not normal; they are a sign that something is wrong with the probe. Also known as "dropout," these lines occur when one of the piezoelectric crystals stops sending and receiving signals. Dropouts often start small and may appear on the side of the screen. While they are relatively harmless at first, they are the initial sign that something is wrong. As the lines become thicker and obscure the image, the chance of missing something important increases. If you see these lines, have the probe serviced immediately.
Recognizing Signs of Probe Lens Failure
The probe lens is small, but it is still prone to pinholes, pitted surface areas, and delamination. These pinholes may not be visible at first, but over time, they will become more prominent. Delamination can affect picture quality, which makes the viewing area harder to see and diagnose. These types of wear can also harbor bacteria and expose other patients to disease.
Checking for Cable Sheath Damage
If you notice cracks and damage to the plastic sheath on the cable, do not dismiss it. Running over the cable with the ultrasound’s wheels and chair legs can cause tears to happen. Overlooking damage to cables can lead to safety issues, as electricity runs through them. Touching the exposed metal can potentially shock the technician and patient.
Inspecting for Torn Strain Relief
The strain relief is the area where the cable meets the probe. Damage to this part is similar to damage to the cable sheath. It is easy to spot because that portion of the probe is handled the most. Once separation from the probe occurs, exposure of the cable can lead to damage. While it may seem like a superficial problem, the more the cables become exposed, the more susceptible the probe is to failure.
