Ultrasound, operating at frequencies below the threshold of human hearing, has emerged as a versatile tool in diverse therapeutic applications. Notably, low-frequency ultrasound at a frequency of 1/3 MHz exhibits unique properties that lend themselves to various clinical uses. These include tissue regeneration, which involves stimulating fibroblast

A high-frequency ultrasonic treatment system operating at a frequency of 1 MHz offers a versatile solution for a broad range of applications. These systems utilize high-intensity sound waves to generate cavitation effects within materials, leading to transformations in their physical and chemical properties. The precise application of ultrasonic e
