Generating Bubbles, Diagnosing by Bubbles, and Treating with Bubble: From Generation of Ultrasonic Contrast Agent to Its Medical Application (1) Microbubble Generation Technique

Abstract

Microbubbles with diameters of less than 1 mm are currently attracting considerable attention because of their properties such as a large surface area per unit volume, low rising velocity, self-pressurization due to surface tension, and acoustic property. In this paper, we introduce some commonly-used microbubble generation techniques for industrial use and medical use.
