An ultrasound scan uses high-frequency sound waves to create an image of the inside of the body. It is safe to use during pregnancy and is also a diagnostic tool for conditions that affect the Ultrasound, on the other hand, gives good contrast between various types of soft tissue. Ultrasonic scanning in medical diagnosis uses the same principle as sonar. Pulses of high-frequency ultrasound, generally above one megahertz, are created by a piezoelectric transducer and directed into the body.

• “Ultrasound” refers to frequencies greater than 20kHz, the limit of human hearing • For Medical imaging typically 100 Times higher frequency than audible by human typically 2 to 20 MHz Transmission and Reflection Medical ultrasound imaging has advanced dramatically since its introduction only a few decades ago. This paper provides a short historical background, and then briefly describes many of the system features and concepts required in a modern commercial ultrasound system. The main disadvantages of ultrasound are the training and skill required of the examiner, low resolution, and the common appearance of artifacts. Technical background Generation of ultrasound waves. Ultrasound waves are high-frequency sound waves above the limit of human hearing (∼ 20 kHz); medical ultrasound employs frequencies ∼ 2–20 MHz) What is an ultrasound? An ultrasound scan is a medical test that uses high-frequency sound waves to capture live images from the inside of your body.
