It is very common these days for expecting parents to have 4D ultrasound scans or bonding scans as otherwise known. 3D/4D ultrasound is an ultrasound scanning technique, often used during pregnancy providing 3D/4D images of the baby.
There are several different ultrasound scanning techniques in a pregnancy ultrasound. The standard common diagnostic scan is the 2D ultrasound scan. In 3D baby scanning, however, instead of the sound being sent straight down and reflected back, it is sent at different angles. The returning echoes are processed by a powerful computer program resulting in a 3D volume image of the baby's surface and/or internal organs.
Clinical use of this technology is an area of intense research activity especially in fetal anomaly scanning but there are also popular uses that have been shown to improve fetal-maternal bonding. 4D baby ultrasound scans are similar to 3D scans, with the difference associated with time.
So 4D ultrasound scans are essentially 2D ultrasound scans and the scanner puts the 2D information together to create a 4D image of the baby.
The ideal time to have a 3D/4D ultrasound scan is between 26 and 30 weeks of pregnancy as the baby skin is better developed to see the face.
This 4D ultrasound scan includes:
2x b/w 3D images in a mounted card frame
1x colour 3D image download to iPod/Mobile
Growth report includes the estimated weight of the baby at current gestation
Well being assessment includes the position of the baby and placental position
Complimentary gender confirmed if requested
No preparation for this scan is necessary, but we recommend that during the week before your 4D scan, you drink a couple of extra glasses of water each day. This will help you to be hydrated and assures that there is sufficient amniotic fluid around your baby which helps with the 4D scan. A full bladder is not required.
From experiences, we know that sometimes chocolates, sweets, fresh orange or even fizzy drinks can help when trying to stimulate your baby to move, so feel free to bring some along to your appointment in case the baby is having a nap. Caffeine is not recommended before your 4D scan.
When you arrive to have a little walk around, this might help wake your baby up before for the scan.
The Pregnancy Ultrasound Scan
Pregnancy or baby ultrasound scans are a very common part of prenatal care. This is because ultrasound scans are completely painless, have no known side effects on mothers or babies, and can be carried out at any stage of pregnancy: in early pregnancy, ultrasound is being used to confirm the baby's heartbeat and exclude any early-stage abnormalities; later in pregnancy ultrasound is being used to evaluate the baby's overall health.
Diagnostic Medical ultrasound scan or medical sonography as otherwise known is a painless imaging technique utilizing sound waves to produce internal images of the body. It is called ultrasound as the sound frequency being used is at the region of 1 to 20MHz. The human ear can't hear these frequencies. The sound waves are produced by the transducer or the probe as most commonly known. As they travel through the body they bounce back to the transducer due to various differences in tissues. The returning echoes are picked up by the probe and a powerful computer analyses the echoes and creates the image on the screen. There are various kinds of ultrasound scans that can be performed and each looks at different organs of the body such as tendons, muscles, joints, blood vessels, liver, kidneys, uterus and ovaries to confirm or exclude possible pathology. Unlike CT and MRI, ultrasound does not use radiation and therefore is pregnancy-friendly. It is also life and is ideal for musculoskeletal exams to evaluate moving joints.
