Basic Principles Of B-ultrasound Diagnosis Technology

Ultrasound imaging diagnosis mainly uses B-type real-time ultrasonic scanner, which is a gray-scale modulation type diagnostic instrument.B type ultrasonic machine uses the pulse current to cause the ultrasonic probe to simultaneously emit multiple ultrasonic waves, detect it on a cross section, and use the reflection of the sound wave to convert into a pulse current signal th rough the probe, and form a light spot with different brightness and brightness on the display screen to display a tomographic image of the position to be probed. Due to the different acoustic resistance values of various tissues of the body, the difference in intensity of sound reflection is exhibited. When detected the no reflection (liquid) and strong reflection (dense tissue), black and white are respectively displayed.
