The importance of ultrasound gel quality

Ultrasonography is a widely used diagnostic method, for example, to perform pregnancy or routine exams. It is an exam that allows you to see any organ or tissue in real time.

To perform an ultrasound, a gel is applied to the patient's skin. Do you know why? Read on ...

What is the ultrasound gel?

The gel is a sticky compound of water and propylene glycol, to reduce static. This texture has a reason. As a thin layer of the product is placed so that the device can slide, it tends to be thick and sticky so that it does not run off the skin during the exam.

Why is it necessary to use the gel?
According to the book “Christensen's Physics of Diagnostic Radiology”, by Thomas S. Curry, James E. Dowdey and Robert C. Murry, the use of the gel is done for two reasons:

• To eliminate the loss of energy at the air-tissue interface, that is, in that minimum air space between the equipment and the skin.

Explanation: What happens, according to the authors, is that the acoustic impedance of the air is extremely low. Therefore, when an ultrasound beam reaches this space between the equipment and the skin, it is reflected almost entirely and the amount of energy that remains after reflection is insufficient, preventing images from being generated.

However, with the use of a gel, which has an acoustic impedance close to that of water, the enormous reflection that happened with the beam is drastically reduced, allowing the amount of energy to be five hundred times greater and, with that, can produce the images .

• To perform the coupling of the material to the body.

Explanation: It must be kept in mind that the piezoelectric crystal, which is in the device's transducer, has a thickness that corresponds only to half the length of the sound waves, which is not enough. Therefore, it is necessary to place a layer in front of the crystal that fits to fill the rest of the space.

As the gel has a thickness of 1/4 of that length, it is perfect for giving this match and maximizing the transmission of acoustic energy to the fabric. That is why, even, patients are advised to go to the exam with a bladder full of water, since this works as a coupling agent, making this space even more filled.

summing up
Considering the above, it is possible to understand that the
ultrasound sound waves hardly travel through the air and that the ultrasound gel is a conductive medium that creates a connection between the skin and the transducer.

Thus, in addition to helping to attach the device to the body so that the sound waves work, it is also responsible for preventing any extra air space between the equipment and the skin, in order to create a clear image.
