4D Ultrasound
Frequently Asked Questions
What is "3D/4D Ultrasound"?
"4D" is shorthand for "four-dimensional” – the fourth dimension being time. As far as ultrasound is concerned, 4D Ultrasound is the latest ultrasound technology and it is exclusive to GE Medical Systems. 4D Ultrasound takes three-dimensional ultrasound images and adds the element of time to the process. The result: live action images of your unborn child or of any internal anatomy.
What are the advantages of the 4D technology?
In contrast to other 3D imaging diagnostic processes, 4D allows your doctor to visualize internal anatomy moving in real-time. For example: Movement patterns of fetuses allow conclusions to be drawn about their development. So physicians and sonographers can detect or rule out any number of issues, from vascular anomalies and genetic syndromes.
Are there any risks related to 3D or 4D ultrasound?
No. 3D and 4D Ultrasound both utilize sound waves to look inside the body. The technology is similar to radar. A probe placed on the body emits sound waves into the body, listens for the return echo, and generates an image.
Does a 4D Ultrasound exam take longer than a traditional ultrasound exam?
No. Even though a 4D Ultrasound exam employs slightly different technology, you should not anticipate a longer exam.
Why do the 4D Ultrasound images have a golden hue?
Physicians have the option of selecting different tints in reviewing images. GE Medical Systems has found that the golden hue is aesthetically pleasing to the eye and shows excellent shadows and highlights.
How long does an ultrasound exam last?
There are many factors that impact the length of an ultrasound exam, including the position of the baby in the womb. However, a typical exam for an expectant mother lasts approximately 30–50 minutes.
Do I have to make any special preparations for an ultrasound exam?
Ultrasound is a safe, non-invasive exam that does not typically require any exam preparation. Still, please consult with your physician first on any requirements.
What are the advantages of the 4D technology?
Displaying the entire volume of an object that is being examined makes it possible to analyze the tissue concerned. 4D allows doctors and sonographers to analyze fetal motion and perform exams previously unavailable.
What is Volume Rendering?
Volume Rendering is the process of capturing ultrasound image information and compiling it into a three-dimensional image. Volume Rendering allows doctors to visualize internal anatomy in every direction.
Beyond pretty baby pictures, are there other applications for
4D Ultrasound?
Yes. The Voluson 730 is a full-service ultrasound system that can be used for breast imaging, interventional urology and general imaging. As with all ultrasound systems, it can be used to research the following:
- Determining fetal age
- Analyzing fetal development
- Evaluating multiple and/or high-risk pregnancies
- Detecting fetal abnormalities
- Detecting structural problem with uterus
- Detecting placental abnormalities
- Detecting abnormal bleeding
- Determining entopic pregnancy and other abnormalities of pregnancy
- Detecting ovarian tumor/fibroids
- Locating the placenta
