Today I am going to be talking about ultrasound. Ultra sound is a sound wave imaging device. Ultrasound is far too high pitched for us to hear and it goes through the skin and bounces around to paint an image. Ultrasound is not always used for monitoring an unborn baby. Scientists did multiple tests on ultrasound and found that it improves brain senses and nerves. Doctors put an ultrasound next to a persons head to contact the brain and it decreased the waves and that did not surprise the doctors that the brain waves were weaker and shorter but what surprised them was crazy. They did multiple tests on a persons senses and made the tests harder and harder. Some of the tests included poking and touching and one was using multiple wind gusts and too see if they could count all of the wind blasts. The doctors found that those with the ultrasound affect did better on the test than the others. Ultrasound can also be used for viewing many injuries and medical problems. Some medical problems that require ultrasound are knee injuries and brain problems. The sound from the ultrasound  bounces within the skin off of every surface and paints an image on a screen. Doctors use this to diagnose many types of injuries, and monitor a baby. Ultrasound is how one can tell what the gender of the baby is and where it is positioned.
