摘要： Electrical interconnects are provided for CMUTs. For example, electrodes within the silicon substrate, such as the electrodes at the bottom of the void below membranes, are interconnected together within the substrate. The interconnected electrode may then be used as the grounding electrode. By providing interconnection within the substrate and below the membranes, space for vias and the associated connection between the electrodes on an exposed surface of the substrate is minimized. As another example, an electrical conductor is formed on the side of the silicon substrate rather than the top of the substrate. Conductors on the side may allow routing signals from a top surface to a bottom surface without large wire bonding pads. Alternatively, conductors on the edge provide additional space for wire bonding pads. As yet another example, polymer material used as a matching or protection layer is formed on the top surface of the CMUT with electrical traces routed within the polymer. By using multiple layers of polymer, multiple layers of electrical conductors may be routed without interference.
摘要翻译： 为CMUT提供电气互连。 例如，硅衬底内的电极，例如在膜下面的空隙底部的电极在衬底内互连在一起。 然后可以将互连的电极用作接地电极。 通过在衬底内和薄膜之下提供互连，通孔的空隙和衬底的暴露表面上的电极之间的相关连接最小化。 作为另一示例，电导体形成在硅衬底的侧面而不是衬底的顶部上。 侧面的导体可以允许从顶表面到底面的路由信号，而不需要大的引线接合焊盘。 或者，边缘上的导体为引线焊盘提供额外的空间。 作为另一个实例，用作匹配或保护层的聚合物材料形成在CMUT的顶表面上，其电导迹线在聚合物内布置。 通过使用多层聚合物，多层电导体可以无干扰地布线。

摘要： A position of an imaging plane relative to a catheter or other probe is aligned with tissue of interest. Ultrasound tissue images may be registered to the catheter position with minimal rotational ambiguity. The spatial position of an ablation catheter or other device with respect to the imaging plane is more accurately determined, allowing a physician to identify specific anatomy in the relative location of a catheter or catheters. Another alternative or additional approach to determining the position of an imaging plane is to determine the relative position of two or more catheters. A catheter associated with imaging is then moved or bent in a direction having a known spatial relationship with the imaging plane. The position of the catheter is relative to each is then determined again to determine the angle or position of the imaging plane. In addition or as an alternative to determining an angular position of an imaging plane relative to a catheter, an ultrasound image of tissue is generated with acoustic elements for position identification. The acoustic elements are used as an imaging transducer array as well as devices for determining relative positions of the catheters.

摘要： Endocavity and invasive catheter transducers for four-dimensional or other imaging are provided. A two-dimensional or other multi-dimensional array of elements is connected with a minimum number of conductors to an imaging system. One or more conductors are used to select an aperture, such as selecting one or more rows of elements for activation. Along a different axis, such as an orthogonal axis, elements are used to image a planar region. By electronically switching the selected aperture, different planes are rapidly imaged. A matrix configuration of electrodes, such as using column electrodes for phased array imaging and row electrodes for selecting an elevation aperture allows for rapid acquisition of ultrasound data.

摘要： Methods and systems for electronically scanning within a three dimensional volume while minimizing the number of system channels and associated cables connecting a two-dimensional array of elements to an ultrasound system are provided. Larger apertures can be utilized with existing 2D transducer electronics, whose purpose is to reduce the number of conductors in the transducer cable, by having the partially beam formed sub-arrays consist of a sub-array(s) of configurable elements. Exemplary 2D transducer electronics include electronics for the entire beam forming process, partial beam forming, e.g. delaying in time and summing of signals, walking aperture multiplexing, e.g. sequential sub-array actuation, sub-aperture mixing, e.g. delaying in phase and summing, time division multiplexing, e.g. sub-dividing and allocating available bandwidth as a function of time, and frequency division multiplexing, e.g. sub-dividing and allocating available bandwidth as a function of frequency.

摘要： Using configurable arrays, synthetic aperture processes may be used along an elevation dimension for increasing resolution. The increased resolution is used for two-dimensional or three-dimensional imaging. Alternatively or additionally, wide band synthetic elevation aperture focusing processes, such as beamformation, are provided along the elevation dimension to increase resolution. In yet another alternative or additional embodiment, a transducer is rotated about a center of the transducer within the elevation and azimuth plane. An aperture associated with the transducer is mechanically or electronically rotated, and ultrasound data acquired associated with a plurality of different positions. The ultrasound data is then used for synthetic elevation aperture processing. In yet another alternative or additional embodiment, multiple scanning modes are provided. In a survey mode, imaging is provided without synthetic elevation aperture processing. For greater detailed imaging, imaging is responsive to synthetic elevation aperture processes with different elevation focusing and scanning.

摘要： Damage to a capacitive membrane ultrasound transducer is prevented. High voltage protection circuitry is connected with the CMUT. The high voltage protection circuitry is integrated into the CMUT or is provided as external circuitry in the transducer or on the imaging systems. Providing high voltage protection circuitry with a CMUT avoids breakdown voltages associated with the CMUT. Since the high voltage protection circuitry is being used with a CMUT, the high voltage protection circuitry works with a preamplifier adjacent to the membranes for impedance purposes. In one embodiment, the high voltage protection circuitry connects between the membrane and the preamplifier, but may connect elsewhere along the transmit and receive path.

摘要： A transducer system and method for harmonic imaging is provided. At least one transducer element is provided. The transducer element comprises two or more stacked piezoelectric layers. Information from each of the layers is independently processed during one of a transmit event, a receive event, and both transmit and receive events. Information from the transducer element is provided to a filter. The filter isolates harmonic information for imaging. By providing a multi-layer transducer element with independent processing for each layer, a wide bandwidth transducer for harmonic imaging is provided. The null associated with most transducers at the second harmonic of a fundamental frequency is removed or lessened.
