Sonography is the use of sound waves to create pictures of things inside the human body that we can't see. You may have heard of ultrasounds, which are used to show pictures of babies still in the womb. Yep, it's pretty cool technology, and medical sonographers are in demand. That's because sonography can show pictures of more than just babies—things like blood vessels, internal organs, tissue clumps, and much more. Sonographers operate ultrasound equipment and provide summaries of their findings. And they must be good with people, since the news they deliver isn't always great. This is a relatively easy way into the medical industry, where the opportunities for awesome careers are virtually endless.
