1-Day ultrasound technical training course

ProbeLogic will be running the 1-Day ultrasound technical training course We are getting more calls from biomedical engineering departments for advice on how best to maintain their ultrasound equipment. With the “tightening of purse strings” more hospitals are relying on their biomedical departments to have a “quick look” before calling the manufacturer. Biomedical engineers are […]

Why Probe Repairs Make Sense

Service contracts are expensive. For the vast majority of end users, their ultrasound systems don’t give any troubles and the only time they see the OEM service technician is for the annual service. So why spend money on a service when you don’t use it? Service Contract VS General Probe Repairs On average, you would […]

Cleaning General Imaging Ultrasound Transducers

We’ve noticed a growing trend recently of probes coming in damaged which can be attributed to a poor cleaning process. What we’ve uncovered is that people are leaving ultrasound gel on the probe or are using alcohol based cleaning products to clean their probes and this is causing damage and reducing its lifetime. This doesn’t […]

5 Signs When You Know It’s Time to Service Your Ultrasound Probes

Much like our cars, we use ultrasound and by extension, its probes (transducers) every day. In fact, according to the Australian Government, in 2013-14 the Medicare Benefits Schedule (MBS) provided rebates on 8,570,775 ultrasound scans making it the second largest service behind diagnostic radiology (x-ray, mammography). Whilst ultrasound clinics are full speed ahead, here’s 5 […]

What Happens When The Lens Is Damaged? Part 2

In Part 1, we explained how a damaged lens can impact the quality of the probe, now we are going to explain the other impacts a damaged lens can have. The first is from an infection control perspective. Looking at the images below you can see a tiny hole in the lens. There are various […]

What Happens When The Lens Is Damaged?

It’s amazing to think a small knock on the edge of the lens can have such big consequences. Yet this is exactly what has happened in the photos below. The probe in question, a Philips C5-1 has suffered what may only look like a superficial dent, something that you would expect it to be able […]

From Strength To Strength [Infographics]

The Story of Probelogic’s Success  It’s incredible to think that 14 years ago, which has gone by in the blink of an eye, Probelogic was created. It was created out of a need to give people an affordable alternative for when their Ultrasound transducer failed. On that time the only option was to purchase a […]

Testing probes for their plane trip back to site

Once repaired, ultrasound probes typically are sent via plane back to the customer. At times there has been concerns that this plane trip can cause issues with oil filled cavity probes such as TEE or some 3D/4D probes. ProbeLogic now have a vacuum chamber suitable to simulate the pressures on board the plane. All probes […]

What is a matching layer?

You have probably heard us speak of a matching layer between the acoustic array and the lens of the probe. What is this mysterious layer? The matching layer helps to couple the acoustic impedance of the lens material with the acoustic impedance of the array itself. This avoids unnecessary reflections at this mismatched impedence boundary. […]

What happens when water gets in the TIP of a TEE/TOE probe?

When water enters the tip of a TOE/TEE probe, usually through a hole in the bending rubber it causes short circuits between elements. This causes several strange artifacts and image degradation. It can clearly be seen as an increase in capacitance on the electro-acoustic test. ProbeLogic can restore a probe suffering from these faults to […]

6T probe with cracks on the insertion tube

This is an interesting problem. Unless you check very closely it is actually quite difficult to see with the naked eye but the probe has a lot of cracking on the insertion tube near the bending bead. This really does highlight the need to do electrical leakage testing on your transducers. For any assistance with […]

Philips L9-3 with Strange intererence

This is a really unusual one. A philips L9-3 with really unusual interference. That interference raining down on the left side and the stringy artifact on the right side are not real, there is nothing against the face of the probe. The acoustic test yields these results: You can view a video of this strange […]

TEE/TOE probe with an amazing amount of damage

This week we got asked if we could perform a repair on this TOE/TEE probe. This is the worst damage to an insertion tube that we have ever seen in our lab. Due to the age of this probe the repair was not economically viable. However from a technical point of view, even damage to […]

What happens when you drop a 3D/4D abdominal ultrasound probe?

Dropping an ultrasound probe is never good. 3D/4D probes however have the extra fragility of mechanical moving parts. The GE RAB4-8 is no exception. We recently recieved a probe which had been dropped and had the following damage: Notice the cracking around the armature. If you have dropped your 3D/4D probe it is important you […]

Results from probe testing

When ProbeLogic test probes in the field, we usually find approximately 40% of probes in use are non diagnostic. Faults include cable breaks, short circuits, weak elements and dead elements but the most common fault is delamination of the acoustic lens.

The effect of a tiny cut at the edge of a lens

Today we had an interesting repair in the lab. The probe is an M4S with a tiny cut in the edge of the acoustic lens which looks like this:   After removing the lens, the corrosion can be clearly seen: After the ProbeLogic lens replacement process the probe is ‘as new’ again:

Why do 3D probes suddenly start to leak oil everywhere?

Why do 3D probes suddenly start to leak oil everywhere? The fill bladders perish chemically with time. Eventually the perished bladder breaks like this: Probe Logic manufacture their own fill bladders in house which are far more chemically resistant. Once it is repaired. It should stay nice and clean and free from deterioration so that […]

B&K probe checking for leaks

Some B&K probes should be fully water proof even on the connector (with connector sealing plate installed). You should be pressurizing the probe and checking for leaks in a water bath. This is what it will look like if you find a leak!

How do you know you’re getting diagnostic results from your probe?

Does you service provider test them? How do they test them? Probably with a tissue equivalent phantom! Tissue equivalent phantom will test: Axial resolution – this is mainly affected by the speed of ultrasound or the pulse width. Lateral resolution – this is mainly affected by the beam width and the processing within the machine. […]
