The room is usually dark so the images can be seen clearly on the computer screen. A technician trained in ultrasound imaging will spread a clear, warm gel on your child's scalp over the fontanel This gel helps with the transmission of the sound waves.
The technician will then move a small wand over the gel. The transducer emits high-frequency sound waves and a computer measures how the sound waves bounce back from the head. The computer changes those sound waves into images to be analyzed.
Sometimes a doctor will come in at the end of the test to meet your child and take a few more pictures. The procedure usually takes 15-30 minutes.
