Coral Gables is equpped with two ultrasound rooms.

Ultrasound scanning does sound waves rather than X-rays to produce images of body organs.    

Similar to sonar used to locate submarines under the sea, ultrasound has been in use since the 1970s, is painless and has no side effects. Ultrasound involves no radiation, and studies have revealed no adverse effects.

A device called a transducer sends the high- frequency sound waves sent through body tissues. The  transducer is placed directly on the skin, which has been coated with a gel.   

The sound waves are reflected by the body's internal structures as "echoes." These echoes return to the transducer and are transmitted electrically onto a viewing monitor. The echo images are then recorded on a plane film and can also be recorded on videotape.
