What des ultra mean in relation to ultrasound?
Best insight from top research papers
Ultra in relation to ultrasound refers to ultrasonic waves or ultrasonics, which are high-frequency sound waves that are used in medical imaging and other applications. Ultrasound waves have frequencies higher than the upper limit of human hearing, typically above 20,000 hertz. These high-frequency waves are used in ultrasound imaging to create detailed images of internal structures in the body. They are also used in various other applications such as communication, filtering, and manipulation of electromagnetic fields. The use of ultrasonic waves allows for higher resolution and more precise imaging compared to lower frequency sound waves. Ultrasonic technology has been developed and improved over the years to enhance the performance and capabilities of ultrasound systems.
