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.

Imaging is made possible by the transmission and return of sound waves of a frequency much too high for the human ear to hear; Audible sound is in the range of 20- greater than 20,000Hz; Allows for the transmission of ultrasound waves into the body. These waves travel a distance where they reach organs/structures within the desired range of imaging. They bounce off the structure, and return to the ultrasound transducer where they are received and turned into an image by the ultrasound system.
