'ULTRA'-sonic is a sound wave with a frequency above the normal range of human hearing. Most humans can hear up to 16,000 Hertz. Young people can hear almost to 20,000 Hertz. Bats and mice and other small critters can hear much higher and use those sounds to 'see' the world around them. An ultrasonic imaging device sends a signal into a medium and then listens for the reflected waves. The more receiving transducers you use to pick up the sound the better you can tell what you are 'looking' at. Reflected waves will reach one receiver before the next based on where the reflecting object is located. Electronics are fast enough to determine the direction and distance to the reflected objects. Also the higher the frequency you broadcast the better resolution you will see. A computer is interfaced with an array of receiving tranceducers and it calculates the direction and distance that the many echos must represent and then it plots the picture of the results. The Image can be displayed or printed.
Magnetostriction is a property of certain materials that causes them to change shape when exposed to a magnetic field. This mechanical deformation can be used in magnetostrictive transducers to generate ultrasonic waves by converting electrical energy into mechanical vibrations. As the material expands and contracts due to the alternating magnetic field, it creates ultrasonic waves that can be used for various applications such as ultrasonic cleaning or medical imaging.
Ultrasonics are used in medicine for diagnostic imaging purposes, such as in ultrasound scans to visualize internal organs and monitor fetal development during pregnancy. It is also used in therapeutic applications, such as ultrasonic lithotripsy to break down kidney stones or in ultrasound-guided procedures for targeted treatments like tumor ablation.
Ultrasonic waves are important in various fields such as medical imaging, cleaning, and industrial testing. They have the ability to penetrate through materials allowing for non-destructive testing and imaging. Additionally, ultrasonic waves can be used for precise material removal and manipulation.
Ultrasonic sound examples include medical imaging, cleaning, and distance measurement. In medical imaging, ultrasonic waves are used to create images of internal organs. In cleaning, ultrasonic waves are used to remove dirt and grime from objects. In distance measurement, ultrasonic waves are used in sensors to determine the distance between objects.
Ultrasonic imaging uses high-frequency sound waves to create detailed images of internal body structures. The principle is based on the reflection and absorption of sound waves by different tissues, which are then processed to generate a visual representation. Ultrasonic imaging is widely used in medical diagnostics due to its non-invasive nature and ability to provide real-time information.
