Ultrasound, 3D, 4D and 5D uses sound waves to capture a high resolution 3D image of the baby inside the womb.
Ultrasound works by listening to sound waves that are directed and bounced off specialized equipment, resulting in an image. In 3D, 4D and 5D ultrasound, these same sound waves are used, but this time they are directed towards several planes, which allows the receiving equipment to “see” the image in three dimensions. Essentially, 3D 4D and 5D is exactly the same as 2D ultrasound, but different software is used to interpret the data collected and create these incredible images.
3D, 4D, and 5D ultrasound use exactly the same intensity frequency as 2D ultrasound, which has been used for decades for routine imaging. Medical professionals generally recognize that ultrasounds are safe and low risk. So there is no need to worry about undiagnosed ultrasounds.
What is the difference?
2D was the standard for ultrasound imaging and sex determination for a long time. However, 2D images can appear flat and often require the doctor to “chase the baby” to obtain an optimal image.
3D ultrasound results in high-resolution three-dimensional images of the baby. 3D images provide a clearer, more realistic first look at your baby.
4D ultrasound adds the dimension of movement, creating a "video" of the baby's movements. With 4D ultrasound technology, still images produced with 3D ultrasound are played one after another, creating a moving image in real time. 4D allows you to see a baby moving, yawning, stretching and smiling in real time.
5D ultrasound adds another layer of realism to the baby's image by producing a three-dimensional image with realistic shades of reddish-pink. The "flesh tone" can give the feeling of looking at the baby right inside the womb.
