TRANSMITTING/RECEIVING DUAL-MODE FOCUSED ULTRASONIC TRANSDUCER AND MICROBUBBLE CAVITATION IMAGE VISUALIZATION METHOD USING SAME

摘要

This application relates to a transmitting/receiving dual-mode focused ultrasonic transducer and a microbubble cavitation image visualization method using the transducer. In one aspect, a plurality of mounting holes are formed in a transducer body with a limited area according to the Fibonacci pattern that allows for the maximum number of objects to be mounted in the transducer body. A plurality of transducer elements are mounted in the mounting holes so as to form a transducer element arrangement having highly nonlinearity. According to various embodiments, microbubble cavitation can be induced and visualized by using a small number of receiving elements.
