Abstract: Disclosed herein is a non-invasive treatment system using intermedium, and an exemplary treatment system is configured to output high-intensity focused ultrasound to remove bone tissue, inject an acoustically-transparent medium into a part where the bone tissue is removed to generate an intermedium, and output therapeutic ultrasound that passes through the intermedium. Accordingly, the bone tissue is removed in a non-invasive way using high-intensity focused ultrasound, and the intermedium is generated at the bone tissue removed site, to increase the penetration of therapeutic ultrasound or generate ultrasound itself, thereby improving an ultrasound treatment effect while minimizing the side effect (for example, infection of dura mater) of invasive surgery methods.
