Ultrasound works by using a “wand” or transducer to send sound waves through the body. The waves bounce back as they hit organs, tissues, and bones to create a visual image. There are two ways ultrasounds are performed:
2D, 3D & 4D Ultrasounds
2D is 2-dimensional meaning the images show length and width but not depth. It’s a regular black and white image. For pregnancy, it shows an outline but it may be hard for you to see the baby
3D is 3-dimensional meaning the images show length, width, and depth. The technician takes several 2D images at various angles then technology translates them into a 3D image. For pregnancy, 3D shows baby’s feet, hands, and other areas the sonographer focuses on
4D is 4-dimensional meaning the images show length, width, depth, and depth-over-time to show motion. This is similar to 3D but it also shows movement and can be viewed as a video. For pregnancy, 4D shows movement like thumb-sucking. 4D is rarely needed for medical reasons and is not covered by insurance.
Ultrasound is used to see how the fetus is developing and to check for potential problems. It also gives us information about things like fetal position, the age of the fetus, and how many there are. You may have at least one general sonogram during your pregnancy.
Our ultrasounds are performed by specially trained, skilled ultrasound technicians, called sonographers.
