How does 3D ultrasound work?

This medical ultrasound technique provides a 3-dimensional image of your fetus

At OMNI Ultrasound & Gynaecology Care in Sydney we offer patients ultrasound scans to evaluate their unborn fetus. This technology allows expectant parents and clinicians real-time view of the fetus during the antenatal period.

The importance of clinical antenatal assessment

Antenatal care is important in helping to obtain the best possible outcome for the mother and child. Traditionally, antenatal care involves a number of routine visits on a regular basis to ensure the health of you and your unborn child.

At OMNI Ultrasound & Gynaecology Care we see pregnant women at:

  • Dating the pregnancy and checking pregnancy viability

This early pregnancy scan is a routine viability/dating scan. This scan is useful for excluding ectopic pregnancy as well as aids in the timing of the 12 week Nuchal Translucency (NT) scan.

  • 10-14 weeks

To assess 2 maternal pregnancy hormones: PAPP-A and free hCG. These are used to measure the chance of your baby having Down’s Syndrome.

  • 11-14 weeks

Routine scanning for Downs Syndrome (NT scan) +/- Consultation and complimentary 3D/4D images.

  • 12-18 weeks

This is when you can undergo Invasive testing such as (CVS or amniocentesis) in case of high risk NT scan results. With invasive tests there is a small risk of miscarriage: approximately 0.5-1%.

OMNI does offer a non-invasive blood test (NIPT) to ascertain the likelihood of your baby having chromosomal problems.

  • 18-20 weeks

Morphology scan is a detailed ultrasound which examines the brain, face, heart, spine, chest, abdomen, stomach, kidneys, bladder, arms, hands, legs and feet.  If you wish we can also tell you the gender of your baby.

You will receive complimentary 3D/4D images.

  • 22-42 weeks

Fetal growth and wellbeing scan assesses the growth and wellbeing of your baby.  This scan is a 3D/4D scan that locates the placenta, measures your baby’s head, abdomen and thigh bone as well as observing your body’s activity.

You will receive complimentary 3D/4D images.

What is 3D ultrasound?

With 3D fetal scanning the soundwaves from the ultrasound are sent at multiple angles instead of straight down. The returning echoes are processed via a 3D ultrasound transducer resulting in reconstructed 3D volume image of your fetus’s surface or internal organs.

Unlike 2D ultrasounds, 3D allows you to see width, height and depth much like 3D movies. The main difference being no movement is shown. 3D ultrasound scan is done through your tummy and involves no risk to your or your baby.

Although the imagery generated by 3D technology at OMNI gives the expecting parents great views of their baby, there is no evidence that this technology adds to the standard 2D ultrasound when assessing your fetus’ anatomy.

OMNI Gynaecology & Ultrasound have an App

Our App allows you to calculate the best time for you to have your scans, as well as interact with the 3D/4D unborn baby throughout your pregnancy.  It has a database of baby names and the definitions of names as well as information of the 2D, 3D and 4D scans that OMNI provides patients. You can download the App here.

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.
