What is the function of the acoustic gel used in ultrasound examinations?

The function of acoustic gel in ultrasound examinations is vital for optimizing image quality. When the transducer is applied to the skin, there is a natural layer of air between the transducer and the skin, which can significantly hinder the transmission of sound waves. The acoustic gel serves to eliminate this air gap, thus ensuring a more effective coupling medium for sound waves. By filling in the space and creating direct contact between the transducer and the skin, the gel facilitates the passage of ultrasound waves into the body and back, allowing for clearer and more accurate imaging. This is essential for the sonography process, as it enhances the quality of the images obtained, leading to more reliable diagnoses.
