　　Pet ultrasound machine, pet store ultrasound machine, pet ultrasound machine, expensive pet ultrasound machine, pet ultrasound machine price, pet ultrasound equipment manufacturer, welcome to inquire! Below we will introduce the reflectivity of pet ultrasound machines.

　　Pet ultrasound will propagate in the medium and reflect when it encounters interfaces with different acoustic impedances. Part of the incident ultrasonic energy will cause echo reflection, while the rest will continue to propagate. If there are multiple different acoustic impedance interfaces in the medium, multiple echo reflections can be generated sequentially.

　　Usually, ultrasound reflected by the acoustic interface can be detected, and the acoustic impedance difference is greater than 0.1%. Ultrasonic diagnosis mainly uses the physical characteristics of interface reflection to determine the direction of a certain part or organ of the animal's body. Transmitting ultrasonic waves and diagnosing the state of the probe part based on the reflected signal, that is, ultrasonic diagnostic technology, the ultrasonic interface must be greater than 1/2 wavelength of the ultrasonic wave to generate emission, otherwise diffraction will occur. If the incident ultrasonic wave is less than half the diameter, a large number of small particles with wavelength will cause scattering. The minimum diameter of the object interface detected by ultrasonic energy is the resolution of ultrasonic waves, which is proportional to its frequency. The theoretical resolution of ultrasonic waves is 1/2 wavelength, and the higher the resolution, the finer the observed tissue structure.

　　When the ultrasound is perpendicular to the interface, the reflected echo can be received and returned to the probe, and the display screen shows that when the incident ultrasound is at a certain angle to the interface but not perpendicular to the interface, it is equal to the probe being unable to receive the reflected echo. If the impedance difference between the media is small but the sound velocity difference is large, in addition to angular reflection, refraction will also occur.
