WHAT IS ULTRASOUND?
Ultrasound is energy in the form of waves. The sound
moves at a frequency too high to be heard by the human ear. By reflecting the inner organs
and being "read" by scanners, the sound wave creates pictures of the internal
organ and the pregnancy, the fetus. Ultrasound differs from X-rays in that it uses sound
instead of X-rays, making it safer for the user and the mother.
