This study explores the biophysical mechanisms by which ultrasound waves interact with biological tissues and analyzes their diagnostic and therapeutic applications in modern medicine. Through theoretical modeling and experimental data, the paper examines the influence of frequency, intensity, and exposure duration on thermal, mechanical, and cavitation effects. The results indicate that ultrasound can modify cellular activity, enhance tissue regeneration, and improve microcirculation when properly controlled. Understanding these principles ensures the safe and effective use of ultrasound technologies in clinical practice.
