Abstract: The present disclosure relates to an acoustic lens using a Fresnel zone plate, a design method and a manufacturing method of the acoustic lens, a focusing ultrasonic transducer to which the acoustic lens is applied, and a manufacturing method of the focusing ultrasonic transducer. More specifically, an acoustic lens using a Fresnel zone plate which is applied to a focusing ultrasonic transducer. The acoustic lens includes a plurality of concentric regions which is concentrically disposed with respect to a center point. In the concentric region, a sound insulation region which blocks an entering sound wave and a transmission region which transmits the sound wave are alternately formed in a radial direction from the center point, and the entering sound wave is focused near a focal point.

Abstract: The present disclosure relates to an ultrasound phantom for a focused ultrasound wave. More specifically, the present invention provides an ultrasound phantom which mimics a body so as to correspond to a speed of sound in the body, in which agarose, sucrose, polydiacetylene vesicle, and distilled water are mixed, and a specific part onto which an ultrasound wave is irradiated by a focused ultrasound transducer is gradually discolored in accordance with a temperature.
