A 4D ultrasound (or 4D Live Imaging)
is
the continuous three-dimensional scanning of the baby with a
simultaneous visualization of the A, B, and C planes. This
revolutionary quad-beam technology, which obtains 3D images in
Real-Time up to 25 volumes per second, goes beyond the boundaries of
traditional ultrasound and opens the 4th dimension of Real Time so
that you can see your baby moving in 3D.
If you are interested in a 4D
sonogram, we can provide 4D ultrasound through live motion capture
technology. We capture these treasured images on DVD, CD- Rom and
photographs. By providing you with high quality digital images its
easy to share your ultrasounds with friends and relatives via the
internet. The optimal time for a 4D ultrasound is between 27 and 32
weeks gestation.
Ultrasound has been in use for over
35 years and no harmful effects have ever been shown from
responsible use. Reputable and responsible 3D/4D centers limit
scanning time to those much less than a typical 2D diagnostic scan.
A 3D/4D ultrasound uses the same exact power levels as the
traditional 2D ultrasound and the FDA sets the standard level that
is safe to be used. While it is sometimes argued by healthcare
providers that 3D/4D ultrasounds are not necessary, studies have
shown a profoundly positive impact on parents and the benefits to
the pregnancy are significant.
When mothers are allowed to see a realistic view into the womb, the
pregnancy becomes more real and often causes mothers to take better
care of themselves. Fathers, extended families and siblings
experience a bonding through viewing a 3D ultrasound session that’s
known to produce a closeness during this very important time in all
their lives.
2D, 3D, and 4D ultrasounds are produced by listening to sound waves.
A 2D visualization is a single plane interpretation of the reflected
sound waves. 3D ultrasound is the same but at multiple angles. These
still images are created through a sophisticated software and shows
detailed features of the baby. 4D ultrasound is referred to as the
“4th dimension in time.” Instead of looking at a 3D still image, you
can view a real-time video with motion of the baby while still in
the womb.
There are several important factors involved when producing a 3D/4D
ultrasound. One factor is the amount of space remaining in the womb.
2D ultrasound sees through everything but when scanning in 3D,
everything becomes solid. Therefore things like the umbilical cord
or placenta can act as a barrier if sitting in front of the baby.
The most optimal time to see the baby is between 26 – 28 weeks
because there is still room in the womb. The further into the
pregnancy you go, the more the remaining space decreases. Another
important factor is how much amniotic fluid is present. It is
important to stay hydrated throughout the pregnancy. Extra fluid
intake a few days prior to coming in for a 3D/4D scan is known to
help with the clarity of the pictures. The placenta position is
another element that effects a ultrasound. An anterior placenta is
on the front side of the womb and in front of the baby while a
posterior placenta is on the backside of the womb and in back of the
baby. With 3D/4D imaging, the posterior is ideal, however it is
possible to capture the baby regardless of which you have and
neither have any health implications.
