Which is deeper 1mhz or 3mhz?
Our primary conclusion is that 3-MHz ultrasound penetrates tissues more deeply than originally theorized. More research with various ultrasound machines needs to be performed to see if 3-MHz ultrasound is more appropriate than 1-MHz ultrasound for producing thermal effects in tissues 2.5 cm deep.
Is ultrasound good for muscle strain?
Therapeutic Ultrasound is the use of sound waves to treat soft tissue injuries, such as muscle strains, tendonitis and frozen shoulder. It is commonly used in physical therapy, along with range of motion exercises, to loosen and elongate muscles.
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 does ultrasound help diagnosis?
Ultrasound imaging uses sound waves to produce pictures of the inside of the body. It is used to help diagnose the causes of pain, swelling and infection in the body’s internal organs and to examine a baby in pregnant women and the brain and hips in infants.
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).
How does the intensity of ultrasound affect the treatment?
Ultrasound Treatment Intensity In a similar way to the pulse ratio decision, the intensity of ultrasound required at the target tissue will vary with the tissue state. The more acute the lesion, the less strong the ultrasound needs to be in order to achieve/maintain the tissue excitement.
How do you calculate the dose of ultrasound?
The most straightforward way to work out a particular dose of ultrasound for an individual patient is to use the combined available evidence and the flowchart below is based on just that. Following the flowchart is a piece of text that explains the process in some more detail.
Is there a dose response relationship for ultrasound?
In the study done by Draper et al., a dose response relationship was established for heating muscle with both 1 and 3 MHz ultrasound.  This allowed clinicians to be able to select both treatment times and intensities that can have outcomes predicting heating in human muscle.
