Ultrasound gel drastically reduces reflection that the air-tissue interface would create, allowing almost 500 times the amount of energy to reach the tissues for generating the image. Thus it is imperative to use a gel in ultrasound. The gel is a type of conductive medium that is used in ultrasound diagnostic techniques and treatment therapies. It is specifically formulated to be as close to the acoustic impedance of the transducer surface and/or soft tissue as possible. The Ultrasound Gel is very useful.
