4D scan images aren’t formed using optical data (like a digital camera) instead they are assembled by sound waves and the final image is a computer rendered 3D image of your baby in the womb.
4D technology uses sound waves that are out of the range of human hearing so your baby will not be aware of the scan taking place. For good clear imaging we need a pool of amniotic fluid around babies face. To get the very best 4D images it’s important that your baby is in a face upward position However the images of your baby’s face will be affected by anything that blocks or reduces the sound waves or causes a shadow, the umbilical cord, baby’s hands and feet. Babies position also plays a large part in the clarity of the images. If baby is cuddled in to the wall of the womb or placenta your imaging will be hazy. We can try to encourage movement by asking you to roll onto your side, sometimes taking a walk around is also needed. Our policy is to try our best for you on the day, unfortunately this means we may over run on our scan times. Please be patient every client is very important to us.
Our Studio is dedicated to 3D 4D scans and as such we do not do any diagnostic scans. However all our sonographers are fully trained in clinical & diagnostic ultrasound and if they feel their could be a problem with baby we will explain as fully as we are able and speak to your midwife with your permission.
All 4D scans start in conventional 2D before switching to 4D. The 2D image show us baby’s position to obtain the best images in 4D. Sexing is always done in 2D.
Switching back and forth between 2D and 4D will happen many times during your scan as the sonographer tries to obtain the best 4D images for you.
Babies can get up to some amazing things in the womb. You may have seen these if you have had a 4D scan in the past. Unfortunately a baby’s performance is never guaranteed and so smiling, yawning, sticking the tongue out. Cannot always be seen in 4D. Sometimes babies just like sleeping.
If your baby is facing towards your back or positioned deep in your pelvis we may only see the back of your baby’s head in 4D. Breach babies are also difficult to scan, as they tend to have both legs up in front of their face. Fizzy drinks chocolate or sweets are sometimes used to stimulate your baby so that they move into a better position, so please bring these along to your 4D scan appointment
