A traditional 2D ultrasound uses sound waves to develop ultrasound images of what’s taking place inside your body. An instrument called a transducer emits high-frequency sound, inaudible to human ears, and then records the echoes as the sound waves bounce back to the transducer creating a two-dimensional image.
Like traditional 2D ultrasounds, 3D and 4D ultrasounds use sound waves to create a realistic surface image of your baby while still in your womb. The difference is that 3D ultrasounds create a three-dimensional image of your baby’s features, while 4D ultrasounds add a dimension of time creating a live video effect, like a movie.
HD is the latest and greatest ultrasound software developed by GE! Similar to your traditional 3D/4D ultrasounds, HD instead uses a virtual light source when imaging. This virtual light source or digital flashlight cast shadows and reflects light onto the image being displayed. This software upgrade also exhibits a bright and vivid bone color giving a more lifelike appearance of your baby.
