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.

In general, ultrasounds (or sonograms) are technically used in medicine to detect changes in appearance of organs, tissues, and vessels or to detect abnormal masses. Most people think of them as what pregnant women get to see the fetus inside their body. However, they have many, many other important uses. Ultrasound scanning is noninvasive and is usually painless. It is widely available, easy-to-use and less expensive than other imaging methods. It can be a safer option since it does not use any x-ray radiation and provides a clear picture of soft tissues that do not show up well on x-ray images. Ultrasounds can provide real-time imaging. Physicians may use ultrasound as a diagnostic tool but itâs not limited to diagnosis.
