ultrasound
B
MRI
C
CAT scan
D
EKG
Explanation: 

Detailed explanation-1: -Diagnostic ultrasound, also called sonography or diagnostic medical sonography, is an imaging method that uses sound waves to produce images of structures within your body. The images can provide valuable information for diagnosing and directing treatment for a variety of diseases and conditions.

Detailed explanation-2: -The sound waves are reflected back to the transducer by boundaries between tissues in the path of the beam (e.g. the boundary between fluid and soft tissue or tissue and bone). When these echoes hit the transducer, they generate electrical signals that are sent to the ultrasound scanner.

Detailed explanation-3: -Ultrasound (also called sonography or ultrasonography) is a noninvasive imaging test. An ultrasound picture is called a sonogram. Ultrasound uses high-frequency sound waves to create real-time pictures or video of internal organs or other soft tissues, such as blood vessels.

Detailed explanation-4: -Ultrasound imaging (sonography) uses high-frequency sound waves to view inside the body. Because ultrasound images are captured in real-time, they can also show movement of the body’s internal organs as well as blood flowing through the blood vessels.

Detailed explanation-5: -Ultrasound refers to any sound waves with frequencies greater than 20kHz. Diagnostic ultrasound typically uses frequencies between 2 and 20 million Hertz (Megahertz-MHz)
