摘要： An ultrasonic emulsion fluid is provided for use in ultrasonic probes of medical ultrasonic diagnostic systems, in which the fluid couples ultrasonic energy between a transducer and human tissue. The emulsion outer phase is a water and velocity enhancer mixture. Suitable enhancers include alcohols such as ethylene glycol, propylene glycol, or glycerol. The suspended phase of the emulsion is an oil phase such as a silicone fluid. The silicone fluid droplets in the emulsion exhibit an average size which provides the emulsion with desired attenuation characteristics over a given band of ultrasonic frequencies.
