When you hear the word “ultrasound,” pregnancy likely comes to mind. It is one of the most common uses of this imaging technology.
During a fetal ultrasound, a sonographer will either place a transducer wand either on your belly or in your vagina (for very early pregnancy). The sonographer may apply a gel over your belly to help the sound waves move more easily.
The transducer will then emit sound waves into your uterus. These will echo off of the fetus’ tissue, bones, and fluids and back to the transducer. Once received, the transducer will translate the echoes into images on the screen. You will see a black and white moving picture. This is a picture of the inside of your body!
