Rather than thinking of ideas in coming up with words to express them, we usually think in words. Inaccurate use of language can harm speakersâ credibility by making them sound less intelligent or ill informed.
Ultrasound is high frequency sound wave with frequencies of 20 kHz or higher. (Fig. 1) Ultrasound has many practical applications. It is often used in cameras to measure distance and used in ships to measure sea depth.However, more interesting applications of ultrasound are in the field of medicine. Using an array of piezoelectric transducers, ultrasound can be used to image the internal organs.Fig. 1) Ultrasound has many practical applications.

Ultrasound - Higher tier. Ultrasound may be used instead of x-rays for certain scans, such as scan of unborn babies. Compared to x-ray photographs, ultrasound scans: Do not damage living cells; Produce images of soft tissue; Medical images from ultrasound. Ultrasound is sent into the patient's body. Some of the ultrasound is reflected at each boundary between different tissues or organs. The depth of each layer is calculated using the time taken for each reflected wave to return.
