Programs that utilize inaudible sound in the frequency range of approximately 20,000 to 10 billion cycles per second which are passed into the abdominal cavity of the mother, echo when they strike tissue, and build an anatomical picture of the developing fetus which can be inspected to monitor growth, movement and position as well as to detect structural abnormalities. Fetal ultrasound may also be used to guide more invasive procedures such as amniocentesis, chorionic villi sampling and fetal blood and tissue collection for analysis or biopsies. Also included are non-diagnostic programs that provide ultrasound examinations.
