Question: what is the difference between 3d and 4d ultrasound pictures?
Answer: With 3D and 4D ultrasound scans, you can see the baby in three-dimensional images. ... The most significant difference between 3D and 4D ultrasound is that 4D allows physicians to “live stream” video of the baby's images. 4D ultrasound is essentially 3D ultrasound in live motion.
