![]() The technologist applies a small amount of gel to the area under examination and places the transducer there. The same principles apply to sonar used by boats and submarines. The transducer sends out inaudible, high-frequency sound waves into the body and listens for the returning echoes. Some exams may use different transducers (with different capabilities) during a single exam. The transducer is a small hand-held device that resembles a microphone. Ultrasound machines consist of a computer console, video monitor and an attached transducer. It allows the doctor to see and evaluate blood flow through arteries and veins in the body.ĭuring an obstetrical ultrasound the examiner may evaluate blood flow in the umbilical cord or may, in some cases, assess blood flow in the fetus or placenta. Obstetrical ultrasound provides pictures of an embryo or fetus within a woman's uterus, as well as the mother's uterus and ovaries.Ī Doppler ultrasound study may be part of an obstetrical ultrasound examination.ĭoppler ultrasound is a special ultrasound technique that evaluates movement of materials in the body. The images can also show blood flowing through blood vessels. Because ultrasound captures images in real-time, it can show the structure and movement of the body's internal organs. Ultrasound exams do not use radiation ( x-rays). A computer uses those sound waves to create an image. The probe collects the sounds that bounce back. High-frequency sound waves travel from the probe through the gel into the body. It uses a small probe called a transducer and gel placed directly on the skin. Ultrasound imaging is also called sonography. It produces pictures of the inside of the body using sound waves. Therefore, you can get 3D and 4D ultrasound while pregnancy as many times your doctor recommends.Ultrasound imaging is a noninvasive medical test that helps physicians diagnose and treat medical conditions. The difference is in the software use and not in the mechanism in which the ultrasounds work.Īlong with checking the details and position of the baby, the advanced ultrasounds are also used to ascertain certain physical anomalies and abnormalities in the baby. In 3D and 4D ultrasounds the sound waves which bounce off the baby for taking the images are decoded in a completely different manner. Neither strong, intense sound waves are used in 3D or 4D ultrasounds nor is higher amount of heat produced in the advanced ultrasounds. Whether it is the 2D, 3D or 4D ultrasound, the mechanism of scanning is the same. The doctor is the best person to ascertain as how many ultrasounds a pregnant woman can need and how safe it would be overall. While some say they are absolutely safe some opine that excessive use might harm the baby. There are different kinds of reactions which come with the safety of 3D and 4D ultrasounds. When it comes to the safety and security of your unborn baby, it is obvious that you need to be extra careful. Safety of 3D and 4D ultrasounds for the mother and the baby Majority of these predictions were made between 11 and 14 weeks, which is in the first trimester. ![]() The rate of correct predictions is quite high. As per a published study, it has been known that women who had undergone 3D and 4D ultrasounds in their first trimester, almost 90% received correct predictions regarding the gender of the developing baby. With traditional 2D ultrasound, the time taken for determining the sex is quite delayed. With the help of 3D ultrasound, it is possible to determine the gender of the growing baby in the mother’s womb.

During this time, the ultrasound will bring some amazing pictures of the baby. The best time to get a 3D/4D ultrasound done during pregnancy is between 26-32 weeks. More advanced the stage of pregnancy, higher are the chances of getting clear images of the baby. With these tests, you can see your developing baby on the screen. What is the best time during pregnancy to get a 3D ultrasound done?Īs mentioned previously 3D and 4D ultrasounds cannot be done at any time during the pregnancy period.
