Final answer:
Option B is the answer. Sonographers are the professionals who use ultrasound to see into the human body. They work closely with physicians to provide valuable diagnostic information.
Step-by-step explanation:
The professionals who use ultrasound to see into the human body are referred to as sonographers. Sonographers are skilled in operating ultrasound equipment and interpreting the images produced by the technology. They work closely with physicians, particularly radiologists, to provide valuable diagnostic information about various conditions. These specialized technicians are trained in the operation of ultrasound machines, which utilize high-frequency sound waves to create images of the body’s internal structures.
This technology is particularly useful and safe for monitoring fetal development during pregnancy. Ultrasound is the least invasive medical imaging technique and does not use electromagnetic radiation, making it a preferred method for examining pregnant women. It's also versatile, allowing not just observation, but also therapeutic applications such as the destruction of cancerous tumors.
