v How does ultrasound work?An ultrasound machine has 3 key essentialparts a display screen, a control panel, and a transducerSpecial water-based gel is applied to the skin, prior tostarting the ultrasoundThe probe (handle) is moved back and forth, sending soundwaves through the skin and musclesThe sound waves are reflected and turned into an image thatthen appears on a TV screenv What happens in during an ultrasound?The ultrasound doctor drapesa cloth over any exposed areas that are not needed for the examThe ultrasound doctor applies a mineral oil-based jelly to your skinThey pass the probe over your skin to obtain the required imagesAfter the images have been acquired and measurements taken, the data is storedon diskYou are given a wipe to clean up and then you can get dressed. v Why isthis technology being used? o To capture live images from inside of a bodyo allows us to see problems within organs,vessels, and tissues – without needing to make an incisiono also uses no radiationo usually painlesso Ultrasound scanning gives a clear picture ofsoft tissues that do not show up well on x-ray images Extremelysafe; it uses no radiation or chemicals, just echoes.
It’s more affordable thanother diagnostic imaging and therefore easily available. It can also be knownas a portable technology. Ø Produced by directing high frequency sound waves at a part ofthe body usually from a microscope attached to a computer – Show real timemovement of body parts like the heart; useful for watching organ function Ø Thistechnology has radically reshaped diagnostics, allowing for a relatively riskfree, accessible and accurate glimpse into the human body. § A helpful analogy.
..Ultrasound works in much the same way that bat’s use sound tofind prey and navigate their surroundings.
