Guest guest Posted September 29, 2009 Report Share Posted September 29, 2009 What is an ultrasound? http://www.medicinenet.com/ultrasound/article.htm Ultrasound produces sound waves that are beamed into the body causing return echoes that are recorded to " visualize " structures beneath the skin. The ability to measure different echoes reflected from a variety of tissues allows a shadow picture to be constructed. The technology is especially accurate at seeing the interface between solid and fluid filled spaces. These are actually the same principles that allow SONAR on boats to see the bottom of the ocean. ____________________________________________________________ Click here to light up your life with a love spell! http://thirdpartyoffers.netzero.net/TGL2241/fc/BLSrjpYQw28P6pncxFjDwjahrjLMHKD9j\ Ut9xNaYAX2fr3NQScnMMNBe8Os/ Quote Link to comment Share on other sites More sharing options...
