Ultrasound has been used for fat measurement since 1965. It is becoming one of the most promising methods for body fat layer measurement, especially for SAT (subcutaneous adipose tissue) measurement. Muscle ultrasonography is simple, accessible, reliable, low-cost, and non-invasive technique that could be used to assess the muscle mass.
Ultrasound Technology & Intelligent algorithm measurement. Ultrasonic waves with high frequencies over 20,000 Hz have the characteristics of directional propagation, reflectivity, and non-invasiveness. Therefore, it is often used for human ultrasound imaging examination.
Sound is a vibration that travels as an acoustic wave in a medium (such as a liquid,gas or solid). All vibrations, including sound, have a frequency, which is a measure of how often it vibrates per unit of time. The frequency unit is hertz (Hz). Humans with normal hearing can hear sounds between 20Hz~20,000Hz.
