Babybond® 4D bonding scans are the original and most popular in the UK. We've successfully performed hundreds of thousands since 2003. Many new parents seek reassurance that their baby's growth is checked by a healthcare professional during a 4D scan, it's why our 4D bonding scans include a growth report and estimated fetal weight as well as beautiful 4D ultrasound imaging. We include showing you the sex of your baby at no extra charge, but if you don't want to know, we can keep things hidden. 

All scans are performed by a qualified Sonographer with obstetric ultrasound scanning experience.

Rescan policy

The quality of your 4d scan is dependant on your baby's position. Whilst obtaining the best results on the day, we may stop scanning and ask you to take a short gentle walk in the local area. If, in our healthcare professional’s opinion, we’re not able to complete the primary purpose of your scan because your baby's position is still not favourable, we may offer you the option of a free rescan appointment. If this is not possible due to your gestation, other options will be discussed with you.

Please note that during the pandemic, we may not be asking clients to take a gentle walk unless clinic times allow. If your baby is not in a favourable position, you will be re-booked for a free rescan. This ensures that we keep you and other clients safe by avoiding multiple people in the clinic at any one time.

Note: 4D clips, appointment times and actual scanning time

The number and length of 4D clips are determined by your baby’s position on the day and our compliance with professional safety guidelines. We therefore operate the As Low As Reasonably Achievable (ALARA) principle i.e. we use the minimum ultrasound scanning exposure time and system settings to fulfill the primary purpose of the scan and always endeavor to provide you with a satisfying and varied amount of recordings on the day. Appointment times include acknowledging informed consent to the scan, the appropriate pre and post scan advice being given to you where necessary as well as the actual scanning time on the couch.

Frequently Asked Questions

Are 4D baby scans considered safe?

The HPA published a report in February 2010 and considers that parents-to-be should be aware of "uncertainties regarding ultrasound imaging....." when thinking about 4D scans.

All of our 4D scans are professional guideline compliant as reported in our news item from January 2013.

What is the difference between diagnostic and non-diagnostic scans?

Any pregnancy scans referred to as "non-diagnostic" should be avoided.

It implies that the (diagnostic) ultrasound equipment is not being used in accordance with manufacturer's guidelines, that the person operating it may not be a health care professional or following their duty of care requirements (i.e. ignoring any incidental findings), may not be professionally insured and are ignoring the fundamental safety guideline set out by the DoH in the UK.

All of our pregnancy scans include a minimum of a well-being check, are carried out by health care professionals who will act upon their duty of care with incidental findings and who can write clinical reports.

Our ultrasound systems are sourced through official channels and are set-up and operated to the manufacturer's guidelines.
