Pregnancy Scans

Although available commercially since the 1960s, ultrasound was not widely accepted until the mid-1970s, when additional advances in technology would contribute to better image quality.

The latest advances in ultrasound are 3D and 4D imaging. To create 3D images, an ultrasound system determines the volume of a subject - for example, a baby. The system then reconstructs the image in three dimensions. As for 4D Ultrasound, cutting edge state of the art ultrasound machines gather 3D volumes and instantly reconstruct them into moving images.

In conventional 2D scanning the ultrasound image is made up of a series of thin slices and only one slice can be seen at any one time. Although the image is very informative the picture you see does not look like a baby.

With 3D ultrasound a volume of echoes is taken, which can be stored digitally and shaded to produce life-like pictures of the fetus.

4D just means that these life-like pictures can be seen to move in real time so the activity of the baby inside your womb can be studied. The result: live action movies of your unborn child.

Traditional 2D scan versus the new 4D scan

Traditional ultrasound images are two-dimensional, forcing a doctor to create three-dimensional images in his/her mind.

 “For the untrained eye, traditional 2D ultrasound images can be difficult to interpret” says Dr Bryan Beattie, Consultant in Fetal Medicine at the Cardiff Fetal Medicine Centre in Spire Cardiff Hospital  ” but, with 4D ultrasound, pregnant women and their families can not only easily identify their unborn babies but can clearly see what they are doing”

If you are pregnant, you are sure to be excited about the arrival of your newborn as you cannot wait to look at your child and hold him or her in your arms. However, while we at innermost secrets cannot speed up your pregnancy, we can offer new parents a chance to witness their new baby before the birth with a 4D scan or 3D baby scan.

It appears that 2D baby scan may soon become a thing of the past, as a 3D scan and 4D scan provide a clearer visual of your child. A 3D scan is more realistic than the 2D picture as it allows you to see a clearer outline of your child's body parts, such as their arms, legs and fingers.

A 4D scan is the ultimate baby scan and is similar to a 3D scan except it allows you to witness the movements of your child. If you opt to have this baby scan here from us at innermost secrets you will witness your child performing actions such as yawning and stretching and will see which position they are lying in inside the womb. Also, due to this fantastic technology you will see a clear image of your baby's face and watch how they blink or cry.

After the baby scan you will be allowed to take the picture of your 3D scan home, or if you purchase the 4D scan you will be able to take a DVD of your baby scan to watch at home. The 4D scan will last for twenty to thirty minutes, allowing you plenty of time to bond with your baby, and providing you with a keepsake that you can hand to your child on their eighteenth birthday.

However, this will not be the only baby scan you should receive during your pregnancy, as it is important a hospital monitors both you and your child during pregnancy, these scans are often done on 2D scans as they are only required to ensure your baby is positioned correctly in the womb, its growth and that they have a regular heartbeat. 3D scans and 4D scans are therefore a courtesy baby scan which allows the parents to bond with their child before the birth. It is advised you have your 4D baby scan between twenty-four to thirty weeks during your pregnancy, as you will be able to see your baby's features more clearly.

We also supply baby scans which monitor the nuchal translucency in the womb; nuchal translucency is a collection of fluid which develops under the skin of a baby's neck and is measured using an ultrasound. If a nuchal translucency scan finds that a baby has an increased amount of fluid under the skin of their neck then this is an early way to diagnose Down's syndrome. The nuchal translucency scan is designed to be used between eleven to thirteen weeks of pregnancy due to the size of the foetus.

Here at innermost secrets we are a health clinic that provides our patients with the best medical care. We are proud to supply the latest 4D scans, 3D scans and nuchal translucency scans for new or existing parents who are expecting a new addition to the family.
