How does ultrasound gel affect the detail of the ultrasound waves?

Ultrasound gel plays a critical role in enhancing the detail of ultrasound waves by improving the coupling between the ultrasound transducer and the skin. The primary function of the gel is to eliminate air gaps that can occur between the transducer and the skin surface. When ultrasound waves travel through air, they are largely reflected rather than transmitted, leading to a loss of detail and clarity in the images produced.

By providing a continuous medium for the ultrasound waves to travel through, the gel allows for better transmission of the sound waves into the body tissues. As a result, the detail and quality of the images obtained during the ultrasound examination are significantly improved. This enhancement is crucial for accurate diagnosis and assessment of internal structures, making the gel an essential component in the ultrasound process.
