- Ultrasound focus, energy, tissue temperature
Hello everyone, I stumble on this forum while searching for reliable explanation of ultrasound thermal energy with regards to temperature increase in superficial human tissue, specifically skin. I have been performing diagnostic ultrasound for almost 30 years, specifically vascular hemodynamics.
I have been reading about Uletherapy for the treatment of aging skin and read some information regarding the specific ultrasound system used for the treatment. Basically it said it differed form diagnostic ultrasound because their ultrasound is focused. Huh? I didn't have a problem with that nugget because I figured it was the marketing of the treatment as to eliminate "just anyone" from performing this service. But, when I read the Q&A page, answered by physicians AND a physicist, where this information was specifically questioned, both the physicist and physician stated that diagnostic ultrasound cannot be focused, and therefor not target a specific skin segment.
It went on to say that diagnostic equipment cannot generate the required temperature to elicit cell turnover (could not raise tissue above 60 degrees Celsius). THAT is when I was triggered. And that is when i started looking into it. Marketing department, okay but shady. A physician though? Sounds like unethical and possibly malpractice. Dont all ultrasound units have an intensity limit of 720 mW/cm2? Does anyone know if the Uletherapy units have a different focus then diagnostic units?
Thanks in advance to anyone who can help.
