For more than 35 years, 2-D ultrasound technology—which translates bouncing sound waves into digital images—has allowed parents to meet the newest members of their family a little ahead of schedule. Today, technology has advanced: 3-D ultrasounds reveal tiny hands, feet, and faces in full-color stills, and 4-D ultrasounds record live streaming video of fetuses in real time so that parents can make their children into prenatal Hollywood stars. Under the supervision of a board-certified physician, diagnostic medical sonographers with more than 10 years of experience reveal womb interiors while up to six adults sit and watch the 37-inch widescreen monitor. 2-D technology allows parents to listen to small heartbeats, and, if desired, lets sonographers determine gender when the baby-to-be is 15 weeks in the making. Stills from 2-D and 3-D scans and movies from 4-D scans can be recorded for parents to take home. All repeat sessions receive 10–20% off, so parents can come back to make sure their little ones are growing strong and refraining from playing video games all day.
