    • A miniaturized micromachined ultrasonic transducer 100 is disclosed herein for implantation in tissue to achieve high-resolution images. An array of ultrasonic transducers 102 is fabricated in a carrier 700 using integrated circuits (IC) technology. The carrier 700 is micromachined into a needle shape with a cross-section small enough for the array of ultrasonic traducers 102 to be inserted into tissue for high- resolution medical imaging. The length of the probe shank portion 106 of the transducer 100 is dependent on the quantity of transducers 102 to be arranged in the array. Compared with commercial intravascular ultrasonic devices, this micromachined ultrasonic imager is small enough to allow monolithic integration of a flexible silicon ribbon cable 504 for electrical interconnection from the array of transducers to external electronic. With the silicon ribbon cable 504 as the connector for the array of transducers 102, a catheter is not necessary.
    • 本文公开了一种微型微加工超声波换能器100,用于植入组织以实现高分辨率图像。 使用集成电路(IC)技术在载体700中制造超声波换能器阵列102。 载体700被微加工成针形,其横截面足够小以使超声波传播器102的阵列插入组织中用于高分辨率医学成像。 换能器100的探针柄部分106的长度取决于排列在阵列中的换能器102的数量。 与商业血管内超声装置相比,这种微加工超声波成像器足够小以允许用于从换能器阵列到外部电子的电互连的柔性硅带电缆504的单片集成。 使用硅带电缆504作为换能器阵列的连接器,不需要导管。

    • Volumetric ultrasound images are obtained using a two-dimensional array transducer to create multiple beams that diverge in a viewing direction to achieve high display resolution real-time volumetric imaging. In one embodiment, ultrasound echoes in a plurality of beams positioned adjacent each other in the elevational direction are projected onto respective planes. The volumetric image is created by combining the planes of projection for all of the beams. As a result, an image having a high resolution can be created in real-time. The area scanned by the transducer is divided into symmetrically arrayed beams so that echoes located at the same distance from the transducer are at substantially the same depth beneath the transducer. In another embodiment, multiple beams scan in respective ranges of scanning depths, and the elevational divergence angle is reduced for deeper ranges of scanning depths. In another embodiment, multiple intersecting or parallel beams are used to create volumetric images.
    • 使用二维阵列换能器获得体积超声图像,以产生沿观察方向发散的多个光束,以实现高显示分辨率的实时体积成像。 在一个实施例中,在垂直方向上彼此相邻定位的多个光束中的超声波回波被投影到相应的平面上。 通过组合所有光束的投影平面来创建体积图像。 结果,可以实时地创建具有高分辨率的图像。 由换能器扫描的区域被分成对称排列的波束,使得位于与换能器相同距离的回波在换能器下方基本相同的深度。 在另一个实施例中,多个光束在扫描深度的相应范围内扫描,并且对于更深的扫描深度范围降低了高度发散角。 在另一个实施例中,使用多个相交或平行的光束来产生体积图像。
