Pregnancy is one of those events that is an adventure. From hearing the heartbeat of your baby for the first time to feeling their first movements, all of these moments are to be cherished.
When it comes to ultrasound technology, the new addition is the 4D ultrasound, which is slowly becoming the new normal. From 3D imaging to 4D live video imaging, technology continues to advance, continually amazing expectant parents.
Today, we will discuss in detail this new type of technology, how it differs from the standard ultrasound, and explore its advantages and limitations.
How Does an Ultrasound Machine Work?
As the name suggests, ultrasound uses sound waves to form images of the baby or internal organs.
An ultrasound machine, also called a sonogram, sends a burst of sound waves through the body. These sound waves bounce off the surface and return to the machine as echoes.
The machine records this data to form an image that can be viewed. Ultrasound technology has been in use for a long time, primarily to monitor the growth of the fetus during pregnancy.
Uses of Ultrasound
Ultrasound has been primarily used to monitor the health of the fetus during pregnancy. It is also used to take baby pictures and videos. A two-dimensional (2D) ultrasound is used to produce a flat picture, similar to what you might see on a television screen.
This 2D ultrasound can be used to assess the position of the baby in the womb, the size of the fetus, and its growth. Growth is measured by the size of the fetus, the placenta, and the amount of amniotic fluid surrounding it. Ultrasound can also help detect abnormalities, such as spina bifida or genetic issues, particularly if there is a history of such problems.
Doctors can also monitor the heartbeat and fetal movements using ultrasound. This helps predict fetal growth and, in some cases, assess the baby’s gender.

What Is a 4D Ultrasound Scan?
A 4D ultrasound scan is an advanced version of the ultrasound that allows you to view live video footage of the fetus in real-time.
“4D” refers to the four dimensions: the first three (height, length, and breadth) are the physical dimensions of the baby, while the fourth dimension is time.
In other words, a 4D ultrasound provides a live, moving video that continuously changes, giving a much more dynamic image of the fetus compared to a regular 3D ultrasound.
In a 4D ultrasound, an image is recorded in real-time, capturing all of the baby’s movements, which can be replayed as many times as the viewer likes. This allows you to see your baby making a range of cute movements and facial expressions that can be cherished for a lifetime.
A 4D ultrasound scan is a revolutionary way to see the baby in its mother’s womb for the first time and connect with the baby before birth.
A 4D Ultrasound Scan Vs. Regular Ultrasound
The 4D ultrasound is an upgraded version of the already advanced 3D ultrasound. As mentioned earlier, a regular ultrasound can produce two-dimensional images of the fetus, while 3D and 4D ultrasounds create clearer, three-dimensional images. The 3D and 4D ultrasounds can also produce more lifelike moving images of the fetus as it moves in the womb.
The primary difference between 3D and 4D ultrasound scans is that 3D produces static images of the fetus, while 4D uses moving images, forming a real-time video of the fetus in the womb.

How Does a 4D Ultrasound Scan Work?
The process of a 4D ultrasound is almost identical to a normal 2D ultrasound, with the addition of the time factor.
The mother lies on the exam table, and the technician may ask her to lift her shirt for the procedure. A gel is applied to the mother’s abdomen to facilitate the transmission of ultrasound waves. The technician or ultrasound machine then uses a small handheld device called a transducer (or probe) to move across the abdomen.
This probe sends out sound waves to measure the fetus in the womb. Unlike a regular 2D ultrasound, this probe takes measurements from different angles to produce a real-time video of the fetus.
The 4D ultrasound machine also uses 3D technology to create three-dimensional images of the fetus, its face, and its environment. This 3D technology also produces high-resolution images of the fetus. The 4D aspect comes from the real-time video that is generated.
As mentioned earlier, 4D means four dimensions, with time being the fourth dimension. The combination of 3D technology and time allows for live, moving images of the fetus.
The results can be viewed in real-time on a screen. You will be able to see your baby’s movements, such as stretching, moving around, or grabbing something. You can even see the facial features and expressions of your baby. You will also be able to determine the gender of the baby if the doctor or technician is unsure after the standard 2D ultrasound.
The video can also be recorded and saved for later viewing. You can choose to receive the video on a DVD or USB memory stick, depending on your preference.
The image quality on a 4D ultrasound is much better than on a regular 2D ultrasound. On a 4D scan, you will clearly see the baby’s face, hands, fingers, and even toes, provided the baby is in a good position.
Benefits of a 4D Ultrasound Scan
4D ultrasound scans offer several benefits for expectant parents. The most significant benefit is the emotional impact, which is described below.
1. Seeing Your Baby Move
One of the most obvious and immediate benefits of 4D ultrasound scans is that they provide a dynamic, real-time video of the fetus. You get to see the baby move, and you can even see their face clearly.
If the baby is a few weeks old, you can observe different facial expressions right from the womb.
4D ultrasound scans also help the mother connect with the fetus, preparing her for childbirth and the environment she is about to experience. If the scan shows abnormalities in the placenta or amniotic fluid, these can be addressed to manage potential childbirth issues.

2. Bonding with Your Baby
The natural advantage of a 4D ultrasound scan is the stronger bonding between the parents and their unborn child. Seeing your baby move, hearing the heartbeat, and observing facial expressions or arm movements creates a deep sense of attachment and joy.
Bonding with your baby before birth helps ease the transition, both physically and emotionally. A stronger attachment to the baby leads to a better birthing and nurturing process.
3. Helping Detect Abnormalities in the Baby
If there are issues with the baby’s growth, 4D ultrasounds can be quite helpful. These scans, combined with traditional ultrasounds, can help identify birth defects.
The primary goal of the 4D scan is to create a moving image of the baby as it moves and expresses itself in the womb. Detecting abnormalities in the baby’s face, heart, and other organs is much easier on a 4D scan compared to 2D and 3D ultrasounds. However, as previously mentioned, these scans should only be used for medical purposes.

4. Capturing Memories
4D ultrasound scans provide a unique opportunity to capture and create memories of the pregnancy. A moving image is a special way to experience your baby for the first time before birth.
You can also record the process and share it with family or even create a keepsake. This is a once-in-a-lifetime experience that you won’t want to miss, providing a sense of fulfillment as a parent.
5. Determining Gender Accurately
While 3D ultrasound scans can be used to determine the baby’s gender, 4D scans make it even easier. Since 4D ultrasound provides moving images, it is much easier to determine the baby’s sex compared to still images. The moving form of a 4D ultrasound offers a clearer view of the genitals.
Possible Risks and Downsides of 4D Ultrasound
The main concern with 4D ultrasound scans is that they are sometimes used unnecessarily. In other words, some people do them as a fun activity without understanding their medical value.
If performed repeatedly and without a medical reason, ultrasounds can potentially harm the baby due to prolonged exposure to sound waves. While the chances are low, this risk cannot be entirely ruled out.
Is a 4D Ultrasound Safe?
A 4D ultrasound scan is generally safe as there is no radiation involved. However, as mentioned earlier, the misuse of the technology can have potential negative impacts on the child.
Because 4D ultrasound uses sound waves for a longer duration compared to 2D scans, there may be some potential risks, though these are still not well understood.
Conclusion
A 4D ultrasound scan is an amazing technology that not only offers a unique experience for parents but also helps them connect with their child in the womb. It’s a must-see experience that will become even more meaningful with the birth of your child.
4D Ultrasound Scan Price
The cost of a 4D ultrasound scan can vary depending on the facility and the quality of the ultrasound performed. On average, a standard 4D ultrasound scan can range from Rs. 3,500 – 4,000.
If you choose to add services like a DVD, USB stick, or other extras, the price may be slightly higher.
