I was reading an article about experiments using ultrasound or frequency used to treat eye problems, ear problems, different cancers, wound healing so on.

I cannot find the article again and wonder if these experiments failed miserably and they stop all research into it.

I guess this assuming cell will response to the energy, frequency or ultrasound? In case like cancer it would have to kill it or disrupted it from spreading to other cells?

As anyone read any articles into this?

You may be thinking of so-called Kanzius therapy, which was being investigated as a means of possibly targeting cancer cells via a radiofrequency device ([a lawsuit](https://www.usatoday.com/story/news/2017/03/10/kanzius-cancer-research-delayed-indefinitely-amid-legal-fights/98846852/) has for now derailed the project).

Kanzius’ idea is different from a treatment already in use, known as radiofrequency ablation of tumors.

I think it may been focused ultrasound.

This is some thing new as I never heard it before.

It may have been focused ultrasound article I was reading.:eek::eek::eek::eek::eek:

\*\*  
\*Is an early stage medical technology that is in various stages of development worldwide to treat a range of disorders.

The mechanism is similar to using a magnifying glass to focus sunlight. Focused ultrasound uses an acoustic lens to concentrate multiple intersecting beams of ultrasound on a target. Each individual beam passes through tissue with little effect but at the focal point where the beams converge, the energy can have useful thermal or mechanical effects.

beams are precisely focused on a small region of diseased tissue to locally deposit high levels of energy. The temperature of tissue at the focus will rise to between 65° and 85 °C, destroying the diseased tissue by coagulative necrosis.

As an acoustic wave propagates through the tissue, part of it is absorbed and converted to heat. With focused beams, a very small region of heating can be achieved deep in tissues. Tissue damage occurs as a function of both the temperature to which the tissue is heated and how long the tissue is exposed to this heat level in a metric referred to as “thermal dose”.

Wide range of possible uses from cardiovascular disease to various types of cancer.

can be applied to cancers to disrupt the tumor and trigger an immune response.

it is similar in concept to focusing light through a magnifying glass.

There is regulatory approval to treat a range of cancers, including breast, kidney, liver, the pancreas and soft tissue sarcoma in Europe and Asia. There is a brain system approved in Europe, Korea and Russia to treat essential tremor, Parkinsonian tremor and neuropathic pain.\*
