Advancements in radio frequency antenna technologies for brain health: diagnosis, treatment, and future directions

초록

The human brain is a critical organ responsible for controlling thoughts, emotions, memory, and movement, and disorders affecting it, such as tumors and neurodegenerative diseases, present significant challenges to healthcare. Current diagnostic and therapeutic methods often lack the flexibility, interactivity, and accuracy required for effective brain health management. Radio Frequency (RF) technology has emerged as a promising tool in biomedical engineering, bridging the gap between medical science and technology. This review focuses on the role of RF antennas in non-invasive brain monitoring, diagnosis, and treatment, emphasizing their potential in applications like Magnetic Resonance Imaging (MRI), radiofrequency ablation, and brain neuromodulation. It explores the advancements in RF antenna design, particularly in terms of miniaturization, flexibility, and biocompatibility, enabling wearable, implantable, and portable solutions for real-time brain monitoring and therapy. Despite their promising potential, challenges such as regulatory compliance, material selection, and data privacy remain significant. This paper provides a comprehensive analysis of RF antenna applications in brain healthcare, highlighting the integration of RF systems with advanced algorithms and emerging materials. It also identifies critical research gaps and proposes future directions to enhance the clinical translation of these technologies, thereby improving brain disease diagnosis and treatment.
