In the world of medical innovation, sound is emerging as a powerful tool for healing. While the idea of prescribing sound as a treatment or healing might seem unconventional, ultrasound neurotechnologies are rapidly advancing, offering new hope for patients with a wide range of conditions. From treating brain disorders to enhancing drug delivery, the potential of ultrasound is vast—and it’s now moving into clinical trials with promising results.
The Evolution of Ultrasound in Medicine
Ultrasound technology has been around for decades, but its applications are expanding far beyond its traditional uses. High-intensity focused ultrasound (FUS), for example, has been used since the 1950s to non-invasively target and destroy specific areas of the brain to treat conditions like movement disorders, psychiatric illnesses, and brain tumors. By converging high-frequency sound waves on a precise target, FUS can modify or destroy tissue without the need for surgery.
Today, the U.S. Food and Drug Administration (FDA) has approved FUS for treating essential tremor and tremor-dominant Parkinson’s disease, as well as for thermally ablating certain tumors. However, the real game-changer lies in low-intensity focused ultrasound (LIFU), which is proving to have even broader clinical applications.

Low-Intensity Focused Ultrasound: A Safer, More Versatile Approach
Unlike its high-intensity counterpart, LIFU doesn’t destroy tissue. Instead, it modulates neuronal activity, making it a promising tool for treating psychiatric disorders, chronic pain, and even neurodegenerative diseases. Clinical trials are currently exploring LIFU’s potential to inhibit brain regions involved in post-traumatic stress disorder (PTSD), anxiety, and depression.
One of the most exciting applications of LIFU is its ability to temporarily open the blood-brain barrier (BBB). The BBB is a protective shield that prevents harmful substances from entering the brain, but it also blocks many potentially life-saving drugs and therapies. LIFU, combined with microbubbles injected into the bloodstream, can mechanically stimulate the BBB, allowing larger molecules like gene therapies, antibodies, and chemotherapies to pass through. This breakthrough could revolutionize the treatment of brain diseases like glioblastoma and Alzheimer’s.
Clinical Trials and Real-World Applications
Several ultrasound devices designed to open the BBB are already in clinical trials. For example, the NaviFUS device is being tested for recurrent glioblastoma and drug-resistant epilepsy, while the SonoCloud-9 device is in phase 3 trials for glioblastoma treatment. Early studies have also shown that repeated BBB opening in Alzheimer’s patients can reduce amyloid plaques, a hallmark of the disease.
Beyond ultrasound, other neurotechnologies are making waves. Non-invasive neurostimulationtechniques, such as flickering lights or multi-sensory stimuli, are being used to modulate brain rhythms in conditions like epilepsy andAlzheimer’s. These therapies aim to enhance memory and cognitivefunction by stimulating gamma-frequency brain waves, which are often weaker in Alzheimer’spatients.
The Challenges of Bringing Ultrasound Therapies to Market
Despite the promising healing results , there are still hurdles to overcome. While ultrasound technology has been around for decades, only a few applications have gained FDA approval. Developing and scaling up medical devices for clinical use is expensive and time-consuming, often requiring hundreds of millions of dollars and over a decade of research.
To address this bottleneck, companies like Openwater are taking a bold step: they’re making their neurotech devices open source. By sharing hardware blueprints, source code, patents, and safety data, Openwater is lowering the barriers to entry for researchers and manufacturers. This approach could reduce the cost of bringing new therapies to market from $658 million to just $10 million, making cutting-edge treatments more accessible and affordable.
B say’s : The Future of Ultrasound in Medicine
As ultrasound neurotechnologies continue to evolve, their healing potential to transform healthcare is immense. From treating brain disorders to enhancing drug delivery, these therapies offer a non-invasive, precise, and versatile approach to healing. While challenges remain, the combination of open-source innovation and ongoing clinical research is paving the way for a new era of sound-based medicine.
In the coming years, we can expect to see more ultrasound-based healing therapies move from the lab to the clinic, offering hope to patients with conditions that were once considered untreatable. The healing power of sound is no longer a futuristic concept—it’s a reality that’s reshaping the future of medicine.
