Ultrasound 1 mhz vs 3mhz
Web4 Mar 2024 · Contrary to what I originally thought, 1 MHz frequency penetrates significantly deeper than 3 MHz. So 1 MHz is great for pain reduction, but can cause different forms of cellular damage should you use it as a skin rejuvenation treatment on your face (as you indicated above). 3 MHz frequency targets shallower areas and this was deemed safe and … WebThe penetration depth and efficiency of heating are both affected by the frequency used. 3 MHz should be used when the tissues targeted are within 2.5 cm. [8] 3 MHz is a much more efficient frequency in regards to heating because it heats roughly 3x faster than 1 MHz. [3] …
