If your provider needs to do an ultrasound in the first trimester, she may use a vaginal probe to get closer to your uterus. Many women will have an earlier 2D ultrasound as well. When you're done, the technician will probably give you a few black-and-white images as a keepsake. You'll be able to hear the heartbeat and if your baby is awake, you'll see movement on the screen. These waves bounce off your baby, and a computer translates the echoing sounds into video images that reveal details of your baby's body, position, and movements.

In a 4D ultrasound, a series of 3D images is put together to form a low-resolution video. 4D ultrasound adds a fourth dimension – time.3D ultrasound uses the same basic idea as 2D ultrasound, but takes many images from different angles and processes them together to create an image that looks like a real photograph.This process creates simple, black-and-white images that create a cross-section view, with bright spots for denser materials like bone. 2D ultrasound is the standard ultrasound that healthcare providers use.
The waves bounce off tissues to create a picture on a screen. The ultrasound machines used for medical imaging use waves between 2 to 20 megahertz – that's about 100 times higher than the top of the range we're able to hear (20 to 20,000 hertz). It works just like the sonar on boats, which use sound waves to locate things underwater. Ultrasound is a way to look inside the body with high-frequency sound waves.
