4D Ultrasound
The differences between 3-D and 4-D ultrasound
3D ultrasound probe will collect series of fetus images and put them through the process
to obtain the 3-dimension images. These images will have the depth (volume)
which is called life-like pictures of the fetus. These images will resemble
the photos of newborn baby. For 4-D Ultrasound, the dimension of time is added,
resulting in the movement of the fetus. This newest technology of ultrasound will
scan 25 of 3-dimension images continuously per second.
Advantages of 4- Dimension Ultrasound
4-D Ultrasound enables us to obtain the movement of the fetus that seems natural.
Usually 3-D ultrasound technique will only provide still images of the part of the baby
such as face, arms or legs. 4-D ultrasound will help us to see the baby when it yawns;
open its eyes, etc. With 4-D ultrasound, all of these movements can be clearly noticed
as if we film them by video camera. When compared to 2-D technique, 4-D will give more
natural images of the baby and help increasing the bonding between the mother and her baby
Apart from this, 4-D ultrasound also use to detect abnormality of the fetus’ internal
organs such as spinal cord and heart, to assist the injection to draw some liquid from
the fetus organ as the ultrasound can give the precise and accurate injection point,
and to measure the volume of the desired organs such as amniotic sac which will enable
doctor to calculate period of pregnancy more precisely, especially when the fetus is not yet noticeable.
The proper pregnancy period to be examined by 4-D ultrasound
4-D ultrasound can be used for examination in any period of pregnancy. The fetus' movement can
be observed in the early period. Later, the whole body of the fetus can be seen if there is enough
quantity of amniotic liquid and if the fetus is in the proper position
Conclusion
4-D ultrasound is the latest technology for examination pregnancy. It enables physicians to
obtain enough information of fetal images in order to improve efficiency for evaluation and
thus improve the quality of treatment and care for the fetus. 4-D ultrasound will increase
the confidence for parents as the images will allow them to understand the fetal condition,
especially if some abnormalities occur and will also help to form the bonding between the
parents and the baby.
