    • Devices and methods for obtaining a three-dimensional image of an internal body site are provided. The subject devices are elongated structures (e.g., catheters) having a plurality of ultrasonic transducers (13, 14) located at their distal end. The configuration of the plurality of ultrasonic transducers may be reversibly changed from a first to a second configuration, where the radial aperture of the plurality of ultrasonic transducers (13, 14) is greater in the second configuration than in the first configuration. A feature of certain embodiments of the subject invention is that the plurality of ultrasonic tranducers are configured in the second configuration as a substantially continuous set of transducers. In using the subject imaging devices, the distal end of the devices is positioned at the internal body site of interest while the plurality of ultrasonic transducers is in the first configuration. The configuration of the ultrasonic transducers in then changed to the second configuration for imaging the internal body site. The subject devices and methods for their use find application in imaging a variety of different internal body sites.
    • 提供了用于获得内部身体部位的三维图像的装置和方法。 主体装置是具有位于其远端的多个超声换能器(13,14)的细长结构(例如导管)。 多个超声波换能器的结构可以从第一配置可逆地改变,其中多个超声换能器(13,14)的径向孔径在第二配置中比在第一配置中大。 本发明的某些实施例的特征在于,多个超声波传感器被配置为第二配置,作为基本连续的换能器组。 在使用被摄体成像装置时,在多个超声换能器处于第一构造的同时,装置的远端位于感兴趣的内部身体部位。 然后将超声波换能器的结构改变为用于对内部身体部位成像的第二配置。 其使用的主题装置和方法可用于对各种不同的内部身体部位进行成像。
