With 4D ultrasound videos, you can watch as your baby is moving in the womb in real-time. The Difference Between 3D & 4D Ultrasounds Although 3D and 4D ultrasounds have the same general purpose and are performed by similar advanced technology, they differ in a very observable way: 3D refers to still images that show the three spatial dimensions for a picture of the whole baby instead of a two-dimensional silhouette from traditional sonograms. Read below for more information on our exceptional HD 4D ultrasound videos. All videos were taken during 3D ultrasound / 4D ultrasound sessions at our facility in Philadelphia, PA. 4D Ultrasound Videos Captured at Our Facility Watch a video or select a video gallery below. We are proud to bring exceptional-quality high-definition 4D ultrasound videos of their babies moving freely without the limitations of still images. Fortunately, we at Fetal Vision Imaging are committed to providing expectant parents and families with the best images of their growing child or children. In the past, parents only had access to 2D black-and-white sonograms, where the child was frequently indistinct from his or her surroundings. However, with new advances in ultrasound technology, we can now offer astonishingly clear and interactive high-definition 4D ultrasound videos of babies in the womb.

Mouthing movement and sucking frequencies remained constant between 20 and 34 weeks.įrequencies of complicated facial expressions such as smiling and scowling may increase with advancing gestation owing to the development of the fetal brain and central nervous system.ĤD ultrasound Fetal brain function Fetal facial expression Fetal neurophysiology Second trimester Third trimester.Ĭopyright © 2014 International Federation of Gynecology and Obstetrics. The frequency of yawning, smiling, tongue expulsion, scowling, and blinking increased with gestational age (P < 0.05). Yawning was significantly more frequent than smiling, scowling, and blinking (P < 0.05), and sucking was significantly more frequent than smiling, scowling, and blinking (P < 0.05). Mouthing was significantly more frequent than the other six facial expressions at 20-24 weeks (P < 0.05). The frequencies of mouthing, yawning, smiling, tongue expulsion, scowling, sucking, and blinking were assessed and the data combined with those expressions observed at 25-34 weeks of gestation in two previous studies (n = 34) to determine the correlation between gestational age and each of the facial expressions. Each fetus was recorded continuously for 15 minutes. The facial expressions of 23 healthy fetuses were examined using 4D ultrasound at 20-24 weeks. To assess the frequency of fetal facial expressions at 20-24 weeks of gestation using four-dimensional (4D) ultrasonography and to determine whether there was any correlation between facial expression and gestational age (20-34 weeks).
