3D/4D views and images of your baby with our App

This technology allows us to provide you with a three dimensional image of your baby. The best time to perform the scan is between 26 – 32 weeks of pregnancy in the context of a medical ultrasound scan.


This is an ultrasound-based diagnostic medical imaging technique used by OMNI’s sonographers during pregnancy to evaluate your unborn fetus. This technology enables visualisation of the fetus in-utero. This process provides clinicians and expecant mothers with real-time views of your fetus during the antental period. For over 35 years, obstetricians have used 2D ultrasound technology during pregnancies, but 3D/4D technology is now readily available.

2D ultrasound

2D ultrasound works by directing ultrasound waves (ultrasonic sound waves) straight down onto the area being examined. These sound waves are reflected back to the 2D ultrasound transducer and recorded, providing the operator with a 2D, black and white image of your fetus.

3D ultrasound

This is a medical ultrasound technique, often used during pregnancy, providing 3-dimensional images of your fetus. The standard common obstetric diagnostic mode is 2D scanning. In 3D fetal scanning, however, instead of the sound waves being sent straight down and reflected back to the 2D ultrasound transducer, they are sent at multiple angles.

The returning echoes are processed by a sophisticated computer program via the 3D ultrasound transducer resulting in a reconstructed three dimensional volume image of your fetus’s surface or internal organs. 3D ultrasounds allow one to see width, height and depth of images in much the same way as 3D movies but no movement is shown. 3D ultrasound was first developed by Olaf von Ramm and Stephen Smith at Duke University in 1987.

The main part of 3D/4D ultrasound scan involves a scan done through your tummy. There is no risk to you or your baby and it should not be too uncomfortable.

4D fetal ultrasounds

A 4D fetal ultrasound is similar to 3D scans, with the difference associated with time. In other words, 4D allows a 3-dimensional picture in real time, rather than delayed, due to the lag associated with the computer constructed image, as in classic 3-dimensional ultrasound.

If you would like 3D/4D views and images of your baby, please let us know and this can be arranged if your baby is well positioned at the time of your morphology or growth scan.

OMNI Ultrasound & Gynaecological Care

Condous performs Advanced Endosurgery procedures for women needing intervention for pelvic masses, adnexal pathology, severe endometriosis or hysterectomy. He also runs ‘Hands on’ Live Sheep Laparoscopic Workshops for gynaecologists at Camden Veterinarian School.
Having completed an undergraduate degree with the University of Adelaide, he left Australia in 1993 and moved to London where he completed his training in Obstetrics and Gynaecology. From 2001 to 2003 Condous worked as a Senior Research Fellow at St George’s Hospital, London. At St George’s he set up the Acute Gynaecology Unit, the first in the United Kingdom. It was also during this time that he developed an interest in Early Pregnancy and especially the management of pregnancies of unknown location (PULs). Condous has developed many mathematical models for the prediction of outcome of PULs which have been featured in numerous peer review journals. In 2005, he returned to Australia where he completed his Laparoscopic Fellowship at the Centre for Advanced Reproductive Endosurgery, Royal North Shore, Sydney.

Condous was appointed as a Consultant Gynaecologist and Senior Lecturer at Nepean Hospital in 2006 and soon was made Associate Professor. In 2010, he was made Departmental Head of Obstetrics and Gynaecology at Nepean Hospital. He obtained the MRCOG in 1999 and was made FRANZCOG in 2005. In 2009, he was awarded his Doctorate in Medicine (MD), University of London, for his thesis entitled: “The management of pregnancies of unknown location and the development of new mathematical models to predict outcome”.

Condous has edited three books including the “Handbook of Early Pregnancy Care”, published over 100 papers in international journals and is internationally renowned for his work in Early Pregnancy. He is the Associate Editor for Gynaecologic Obstetric Investigation, which is a European based journal, as well as the Australasian Journal of Ultrasound in Medicine (AJUM). He is on the organising committee and is an invited speaker at the International Society of Ultrasound in Obstetrics and Gynaecology (ISUOG) Scientific meeting in Sydney 2013. His current research interests relate to the management of ectopic pregnancy, 1st trimester growth, PULs and miscarriage and the use of transvaginal ultrasound (in particular sonovaginography, to predict posterior compartment deep infiltrating rectovaginal endometriosis).Condous is also actively involved with post-graduate education including the annual running of the Early Pregnancy and Gynaecological Ultrasound Interactive Courses for Sonologists, Radiologists, Sonographers and Gynaecologists in Australia.
