BME352: The sound waves are reflected or bounced off from internal organs and tissues, and the waves are recorded and displayed by a computer: Cardiovascular Bioengineering Report, SUSS, Singapore

Ultrasound imaging uses high-frequency sound waves that pass through the body. The sound waves are reflected or bounced off from internal organs and tissues, and the waves are recorded and displayed by a computer. Ultrasound scanners usually consist of a computer, video screen, and transducer. The transducer is a small, handheld device about the size of a bar of soap, attached to the scanner by a cord. The transducer generates the sound waves and detects them when they are reflected. Most ultrasound exams are done by moving the transducer on your skin over the area to be examined.
