Sound waves that paint a picture inside your body — in real time.
The Physics of Sound Waves

- These waves travel through your tissues and bounce back when they hit a boundary, such as fluid or solid organs.
- The device records these echoes and uses them to construct a live image on a monitor.
- No radiation is involved, making this a safe way to see inside you.
