Focused ultrasound

Focused Ultrasound is a therapeutic technology that uses ultrasound to target tissue deep in the body without incisions or radiation. It is an early-stage, non-invasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with a variety of medical conditions.

History[edit | edit source]

The concept of focused ultrasound was first proposed in the 1940s, but it was not until the late 20th century that significant advancements were made in the field. The development of Magnetic Resonance Imaging (MRI) in the 1970s and 1980s provided a means to monitor and control the treatment in real time, leading to the first FDA approval of a focused ultrasound device in 2004.

Technology[edit | edit source]

Focused ultrasound works by focusing 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. This technology can be used to destroy tissue, such as tumors, or to stimulate the body's response to disease.

Applications[edit | edit source]

Focused ultrasound is currently approved in the United States for the treatment of uterine fibroids and bone metastases. It is also being investigated for the treatment of a variety of other conditions, including Parkinson's disease, Alzheimer's disease, and essential tremor.

Future[edit | edit source]

The future of focused ultrasound is promising, with ongoing research exploring new applications and improving the technology. The Focused Ultrasound Foundation, a global nonprofit dedicated to accelerating the development and adoption of focused ultrasound, is leading efforts to advance this field.
