At which megahertz MHz will the ultrasound treatment produce the deepest therapeutic benefit?
Ultrasound devices have been described as producing therapeutic heating at depths between 1 and 2 half-value depths. Therefore, 1-MHz continuous ultrasound, with a half-value depth of approximately 2.3 cm, is frequently used to treat deep tissues that are approximately 2.3 to 5 cm deep.
Which two frequencies are useful for ultrasonic therapy?
Beyond this upper limit, the mechanical vibration is known as ultrasound. The frequencies used in therapy are typically between 1.0 and 3.0 MHz (1 MHz = 1 million cycles per second).
What is nonthermal ultrasound used for?
Nonthermal levels of ultrasound are reported to modulate membrane properties, alter cellular proliferation, and produce increases in proteins associated with inflammation and injury repair. Combined, these data suggest that nonthermal effects of therapeutic ultrasound can modify the inflammatory response.
Can you use 1 MHz ultrasound on face?
Microfocused ultrasound has emerged as a safe and effective technology and is currently the only method of achieving lift and tightening of lax skin on the face and neck. Its use in cosmetic medicine continues to grow.
How often can I use therapeutic ultrasound?
According to Rosenzweig, “Therapists use ultrasound anywhere from six to 12 sessions – it’s part of the patient’s therapy, so therapists might do it for five minutes, then perhaps twice a week anywhere from thee weeks to six weeks.
Is ultrasound high or low frequency?
Ultrasound typically used in clinical settings has frequencies between 2 and 12 MHz. Lower frequencies produce less resolution but have greater depth of penetration into the body; higher frequencies produce greater resolution but depth of penetration is limited.
Can you use 1 Mhz ultrasound on face?
Does ultrasound help with inflammation?
Ultrasound (US) therapy is used to reduce pain and inflammation and to accelerate healing after soft tissue injury.

What are the benefits of 3 MHz ultrasound?
The 3 MHz units are designed to be used for superficial tissue problems and cosmetic problems like facial wrinkles and skin discoloration. Ultrasound has three primary benefits that can be helpful to Dupuytren’s contracture and Peyronie’s disease: 1. Speeding up the healing process from the increase in blood flow in the treated area.
Why are 3MHz ultrasound machines used for dupuytrens?
For this reason any US machine used to treat Dupuytrens and Peyronies must have a particular frequency range to keep the therapeutic effect closer to the skin surface where the DC and PD problems are located. This is where the 3MHz US machines come in.
What’s the normal sound range for ultrasound therapy?
Ultrasound therapy. The normal human sound range is from 16Hz to something approaching 15-20,000 Hz (in children and young adults). Beyond this upper limit, the mechanical vibration is known as ULTRASOUND. The frequencies used in therapy are typically between 1.0 and 3.0 MHz (1MHz = 1 million cycles per second).
