What is Ultrasound and how does it work?
Ultrasound uses high frequency sound waves to image the inside of your body projecting the pictures onto a screen. Ultrasound does not use radiation, is painless and can be carried out with movement.
A sonographer, a health professional trained in ultrasound will perform your scan. The sonographer will use a plastic soft hand-held transducer transmitting high frequency sound waves into your body. The sound waves reflect from different tissues in characteristic ways. The different reflection rates are converted into electrical impulses that produce the moving image seen on the monitor.
The sonographer will ask you to lie down on bed and the area to be examined will be exposed. Gel is applied to the skin allowing the sound waves to pass more easily through the body. The transducer (smooth plastic handheld device) is moved around the area of interest. Images are recorded. The procedure usually takes no longer than 30 minutes.
