Portable X-ray Photo densitometry for Children use
The principle of the portable bone densitometer for children is to measure the ultrasonic velocity along the direction of the tibia or tibia by axial reflection technique, and calculate a set of parameters to reflect the bone condition. When ultrasonic waves are incident from a wave of medium to a dense medium, reflected and refracted waves are generated at the interface of the two media. As the incident angle increases, the angle of refraction also increases. When the incident angle reaches a certain value, the direction of refraction is exactly parallel to the direction of the bone surface, and after a certain distance on the bone surface, the same exit angle is used. The bone surface is shot. The propagation time of the first arrival signal can be measured and used to calculate the speed. This velocity can directly reflect the size of the bone density, and when the bone density decreases, the ultrasonic conduction velocity decreases.
