What frequency defines mechanical radiant energy as ultrasound?

Ultrasound is defined as mechanical radiant energy that operates at frequencies greater than 20 kilocycles per second, or 20 kHz. This definition sets ultrasound apart from other sound waves, as it is above the human hearing range, which typically caps at around 20 kHz. The use of ultrasound technology spans various fields, including veterinary medicine, where it is utilized for diagnostic imaging and therapeutic applications.

The distinction of ultrasound as energy above this threshold is significant because it enables the production of high-frequency sound waves that can penetrate tissues and provide valuable information for clinical assessments without invasive procedures. This frequency characteristic allows for clearer imaging and better resolution in diagnostic applications, making it a vital tool in veterinary practices for various examinations, such as pregnancy diagnostics in animals or assessing internal organ health.
