What is an image produced by sound waves called?

• A. Ultrasound
• B. Sonogram
• C. Radiograph
• D. CT Scan

Answer: (B)

Images produced by listening to echoes of sound waves are called a sonogram. In ultrasound, a transducer sends high-frequency sound pulses into the body and then detects the echoes that bounce back from tissues. The timing and strength of these echoes are processed to create an image, the sonogram. The term ultrasound refers to the technique itself, not the image. The other options describe images from different methods—radiographs and CT scans use X-rays, not sound.
