What is ultrasound?
Ultrasound technology uses high-frequency sound waves to create images of internal structures. A small, handheld device called a transducer is used to send sound waves out and also to receive and record the sound waves when they bounce back. The sound waves used in 2D and 3D/4D ultrasound are the same. The difference lies in the sophistication of the transducer and the computer software within the ultrasound machine. Our ultrasound machine is a highly specialized computer that translates the returning sound waves into images for viewing on its computer monitor.
Ultrasound is sound that occurs above the normal range of human hearing. Impact, turbulence, electrical arcing, and friction produces sound all along the spectrum. The machines and equipment comprising industrial systems generate great amounts of human audible sound and ultrasound when in operation.
Diagnostic ultrasound is the use of high frequency sound waves to visualize structures within the body. A small device called a transducer is used to send sound waves into the body, which are then reflected off of internal structures. The returning sound waves (echoes) are captured by the same transducer and sent to the attached equipment which electronically changes the echoes into a picture (image) of the internal structures.
