What does the gel for ultrasounds do?

In: Uncategorized [Edit categories]

Answer:

The purpose of ultrasound gel is to act as a coupler. This allows the sound waves to be carried below the surface of the skin. Since the waves travel poorly through air, there must be a medium to carry the energy from the transducer head to the skin. It is important that air bubbles are not entrained in the gel as this can affect the resolution of the scan.
