Abstract
Ultrasound machines use sound waves to take a look inside your body. These sound waves are very high pitched and cannot be heard or felt. They are generated by an ultrasound machine that uses crystals at the end of an ultrasound probe. These waves pass through your skin and as they reflect back to the machine from tissues in your body, the machine turns them into an image. In this article, you will learn about the different uses of ultrasound, like seeing babies inside the uterus or examining important body organs in patients who are feeling sick. You will also learn about the safety of ultrasound in case you ever need to get one. Last, we will explore the future of ultrasound in medicine by learning about point-of-care ultrasound, or POCUS, which is making it easier for children and grownups to get ultrasounds when they need them!
