As the baby yawns and wiggles his or her fingers, a chorus of coos fills the room. As she peeks in on her child months before his or her birth, the mother-to-be points out similarities between her own nose and the tiny one that's displayed in the 3D image onscreen. The technician smiles and moves the ultrasound device to reveal a more complete view of the baby's face as family and friends look on.

Precious Peek 4D Ultrasound hosts these seemingly miraculous occurrences five days a week. With scanning technology similar to that of traditional 2D ultrasounds, the staff can give eager parents a real-time 3D glimpse of their babies. They preserve records of the session with photographs in a variety of packages, which range in complexity from 2D pictures that disclose the child's gender to bundles that include CDs, DVDs, and a press-conference reporter to jot down the baby's first statement. Based on the expectant mom's due date, a Peek Calendar determines the optimum time for an appointment, during which up to 12 guests can gather to view the images as they are projected theater-style.
