What is the Gel that is applied before an Ultrasound Scan?
Ultrasound is a special form of technology that sends pulsing sound waves at a high frequency deep into the tissue of a patient using a probe or a transducer. The gel is rubbed onto the skin to help the transducer easily glide along the surface. The device can receive and also send sound waves, which then appear as images that are seen on a computer screen. A sonographer looks at the images to make sure that everything appears normal. This is done in real time and the person operating the ultrasound technology can move the transducer or the probe as required to get a fully defined picture of what’s happening beneath skin level. Screenshot images can also be taken and printed out if required.
The gel has a shelf life of approximately 5 years if the bottle remains unopened. Once opened, however, it’s recommended that it be used up within 28 days for the purpose of infection control.
Another thing that can get in the way of reducing clear images is static electricity. Ultrasound gel eliminates the static so that the procedure can be done effectively without any risk of static getting in the way.
