Language does not simply mirror reality, it helps create our sense of reality by giving meaning to events. 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 is widely available, easy-to-use and less expensive than other imaging methods. Ultrasound imaging is extremely safe and does not use any ionizing radiation. Ultrasound scanning gives a clear picture of soft tissues that do not show up well on x-ray images. Ultrasound is the preferred imaging modality for the diagnosis and monitoring of pregnant women and their unborn babies.
