AI-Powered Real-Time Simulation for Focused Ultrasound Therapy

Ultrasound Therapy

A research team led by Dr. Kim, Hyungmin of the Bionics Research Center at the Korea Institute of Science and Technology (KIST) has developed a real-time acoustic simulation technology based on generative AI to predict and correct the distortion of the ultrasound focus position caused by the skull in real-time during focused ultrasound therapy.

The field of medical technology continues to evolve, with one of the most promising advancements being the application of focused ultrasound therapy. This non-invasive approach targets precise areas of the brain, penetrating deep tissues without the need for surgical intervention. Developed to treat a spectrum of neurological disorders including Alzheimer's disease and depression, focused ultrasound therapy offers significant advantages by minimizing harm to surrounding healthy tissue and reducing potential side effects such as infections.

#### Challenges in Focused Ultrasound Therapy

Despite its potential, the widespread adoption of focused ultrasound therapy has been hindered by technical challenges, particularly in accurately targeting ultrasound waves through patients' varying skull shapes. Traditionally, navigation systems relying on pre-treatment medical imaging have been employed to approximate the position of ultrasound transducers relative to the patient. However, these systems often fail to account for real-time distortions caused by the skull's acoustic properties, limiting their effectiveness in clinical practice.

#### Breakthrough in Real-Time Simulation Technology

Addressing these limitations, a research team led by Dr. Kim Hyungmin at the Korea Institute of Science and Technology (KIST) has developed a groundbreaking real-time acoustic simulation technology. Powered by generative AI, specifically a generative adversarial neural network (GAN), this innovative approach predicts and corrects ultrasound focus distortions induced by the skull during therapy. Unlike previous methods that required substantial computational time, this AI-driven model reduces the update time of three-dimensional simulation data from 14 seconds to an impressive 0.1 seconds.

#### Validation and Clinical Application

The effectiveness of the AI simulation model has been rigorously tested, demonstrating an average maximum acoustic pressure error of less than 7% and a focal position error of less than 6mm—both well within acceptable ranges for clinical application. This advancement not only enhances the accuracy of ultrasound treatment but also enables clinicians to dynamically adjust treatment parameters in response to real-time feedback from the simulation-guided navigation system.

#### Implications for Future Healthcare

Dr. Kim envisions broader applications of this technology in clinical settings, anticipating improvements in treatment accuracy and patient safety. The ability to rapidly adapt ultrasound focus based on real-time simulations opens new possibilities for personalized medicine, allowing healthcare providers to tailor treatments more precisely to individual patient needs. This capability is particularly crucial in managing unforeseen challenges that may arise during therapy, ensuring optimal outcomes for patients undergoing focused ultrasound treatments.

#### Future Directions and Expansion

Looking ahead, the research team plans to expand the system's capabilities by testing it in diverse clinical environments and with multi-array ultrasound transducers. By validating its performance across varied conditions, they aim to establish the reliability and versatility of AI-driven real-time simulations in enhancing focused ultrasound therapy's clinical utility. As these advancements continue to refine treatment protocols, the potential benefits for patients with neurological conditions are expected to grow exponentially.

#### Conclusion

In conclusion, the integration of AI into focused ultrasound therapy represents a transformative leap forward in medical technology. By overcoming longstanding challenges associated with skull-induced ultrasound wave distortions, this innovative approach promises to elevate the precision, safety, and efficacy of treatments for neurological disorders. As Dr. Kim and his team continue to refine and expand this technology, the future holds promise for further breakthroughs in healthcare, where AI-driven innovations continue to redefine the boundaries of what is possible in medical care.

This pioneering work not only underscores the power of AI in revolutionizing patient care but also sets a precedent for future advancements in medical technology aimed at improving the lives of individuals worldwide.
