Final answer:
The correct diagnostic procedure to measure signals from sound waves and examine organs and fetuses is Ultrasongraphy. It uses high-frequency sound waves to generate real-time images of anatomy and physiology. It is commonly used in sensitive situations such as pregnancy.
Step-by-step explanation:
The correct diagnostic procedure to measure signals from sound waves and examine organs and fetuses is Ultrasonography. Ultrasonography uses high-frequency sound waves to generate real-time images of anatomy and physiology. This technique is commonly used in sensitive situations such as pregnancy to study fetal growth and development, as well as to monitor heart function and blood flow in the body.
