Ultrasound uses high frequency sound waves to image internal organs. Â Images are created by sending sound waves into the body and then listening for their “echo”. Â TheÂ sound waves are sent into the body by placing an ultrasound probe on theÂ skin. AÂ warm gel will be placed between the skin and probe to facilitate transmission of the sound waves. Â The same probe listens for the echoes returning from the body. Â Only structures under the probe are imaged so the probe will be moved around the body by one of our experienced sonographers to completely image the areaÂ of interest.
