High Intensity Focused Ultrasound:


Ultrasound focusing has good tissue penetration and energy storage. The host generates high-frequency electrical signals, which are converted into focused ultrasound by transducer. The ultrasound is transmitted to the lesion tissues by circulating water system, sound transmission membrane and contact coupling agent. Ultrasound can produce thermal effect, mechanical effect, cavitation effect and biochemical effect in biological tissues. Polaris uses these characteristics to act on pathological tissues to degenerate them, promote tissue reconstruction and improve microcirculation to achieve therapeutic purposes.
