Friends and family members perch on comfortable couches as a 4-year-old boy peers excitedly at a 100-inch screen, anxious to catch the first glimpse of his new brother or sister. The plush theater at Vegas Baby! 4D Ultrasound can accommodate up to 15 friends and family members along with the mommy-to-be, giving them all up-close introductions to the new baby in strikingly detailed 2-D, 3-D, and 4-D images gleaned using GE Voluson Ultrasound System technology. Their system's clear images reveal specifics such as gender, heart rate, or secret handshakes between fetal twins. The specially trained ultrasound technicians boast a 99.9% accuracy rate on gender identification, and they'll schedule a complimentary second appointment if they are not able to identify the gender at 13 weeks or later. They can also develop images into black-and-white or color prints, DVDs, and personalized jewelry.
