Question

Which type of rays are produced in Sonography:
A. microwaves
B. infrared waves
C. sound waves
D. ultrasound

Answer 1

Hint: In sonography, high frequency waves are used to view interior organs in our body. This is a type of medical test in which no radiation exposure is produced. In the medical field, sonography is also known as Ultrasound.

Complete step by step answer:
Sonography is a type of medical test in which high frequency ultrasound waves are used to view the interior of our body and detect the defect if any. In the medical field, it is commonly known as “Ultrasound”.
Sonography is a safe and painless process that can produce live series photos of the internal body with the help of ultrasound waves. Ultrasound imaging, conjointly known as ultrasound scanning or imaging, involves the utilization of a tiny low electrical device/transducer (known as probe) and ultrasound gel placed directly on the skin. High-frequency ultrasound waves are transmitted from the probe through the gel inside the body. The probe collects the sounds that make a comeback and a laptop then uses those sound waves to form a picture. Ultrasound tests don't use radiation (as utilized in x-rays), which results in no radiation exposure to the patient.
Hence, option D is correct.

Note: Ultrasound or sonography is a very effective medical tool that helps in diagnosing the body and treatment of the medical conditions. This is because, unlike X-ray tests, it produces live images of the internal parts of the body which can be seen on a computer screen.
