I’ve been told my probe lens requires replacement. But is it really important?

I’ve been told my probe lens requires replacement. But is it really important?

Do you really need to do it? But why?

Lets start by looking at what can happen underneath the lens of your ultrasound probe. Here is a picture of a phased array ultrasound probe with a tiny little cut in the corner and then the resultant corrosion on the acoustic array because it was not dealt with quickly:

So by ignoring the lens damage, fluid ingress will result which is a massive cross contamination hazard but also will damage the array which will then become a more expensive repair or result in the probe being non economical to repair.

Here is a couple of other examples where fluid has entered a lens and caused damage:


In addition to the obvious cross contamination hazard, there is an electrocution hazard presented by a damaged lens. In this video we show a scenario with a double fault. The lens of the probe has a failure and so does the ultrasound machine. Glad this was in a controlled environment and not on a patient!

Even sealant missing from around the edge of the probe can cause corrosion to the array as can be seen in this case study

So you’ve been told probes can’t be repaired? We have heard that so many times before. Not true! here is a before/after image of a lens that we recently repaired:




Frequently Asked Questions:

So what should you be looking for and checking regularly on your ultrasound probes? Here is a guide
How should you be cleaning your general ultrasound probes? Here is a guide
Sometimes it isn’t always as simple as looking for dropout. In this case you can see that phased array probes dont show dropout clearly.
It really does make sense to repair your probes instead of taking large service contracts with the OEMs. Especially if you have a fleet of machines so that you can spread your risk. Become your own insurance company with very little risk! Here is some information on this approach
