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 an imaging modality that utilizes high-frequency sound waves to provide cross-sectional images of the body. The ultrasound machine has the following components: monitor, keyboard, processor, data storage and probe or transducer. A transducer performs two functions: it emits sound waves (echoes) at a certain frequency and captures the returning echoes at frequencies dependent on the tissues through which the waves traverse. The sound wave that is returned to the transducer is digitized to appear as echoes or dots on the screen.
