摘要
The present invention relates to an acoustic lens using the Fresnel zone plate principle, a method of designing the acoustic lens, a manufacturing method, a focused ultrasound transducer to which the acoustic lens is applied, and a manufacturing method of the transducer. More particularly, the present invention relates to an acoustic lens applied to a focused ultrasound transducer, which has a plurality of concentric circular regions arranged concentrically with respect to a central point, wherein the concentric circular region has a sound insulation region And a transmission region through which a sound wave is transmitted are crossed, so that an incident sound wave is converged in the vicinity of the focal point. The present invention relates to an acoustic lens using the Fresnel zone plate principle.
