摘要： A backing block composite is provided. A transducer is manufactured to include the backing block of composite material. One constituent material provides a skeleton or matrix for enclosing volumes or pockets of another material. The materials are incompatible for bonding, so do not adhere to each other. For example, silicone microspheres are mixed with a nonsilicone resin, forming silicone pockets within the resin. Since the silicone does not adhere to the resin, the silicone may vibrate or otherwise move relative to the cured resin matrix, causing friction between the two materials. As acoustic energy propagates into the backing material, the composite structure of incompatible materials attenuates the acoustic energy as frictionally generated heat between the two material, or through other processes.

摘要： A phased-array ultrasonic transducer assembly includes a catheter. An end portion is mounted to the catheter around a transducer array, and the end portion defines an acoustic window which is essentially non-focusing to ultrasonic energy passing therethrough. Because the acoustic window is non-focusing, a relatively small radius of curvature can be used on the radially outer surface of this window.
摘要翻译：相控阵超声波换能器组件包括导管。端部部分围绕换能器阵列安装到导管，并且端部部分限定基本上不聚焦到穿过其中的超声波能量的声窗口。由于声窗是非聚焦的，所以可以在该窗口的径向外表面上使用相对较小的曲率半径。
