摘要： A multi-dimensional transducer array has pitch along one dimension less than the pitch along a second dimension. The multi-dimensional transducer array with the same or different pitch is manufactured from a plurality of modules. Each of the modules are separately diced and then aligned and combined. Elements of a transducer array are used for isolating a transmit channel from a receive channel. Separate signal lines or traces are provided individually for each element on opposite sides of each element. A transmit channel may connect to one electrode on an element, and the receive channel may connect to an opposite electrode on the element. A multi-dimensional array is provided for time division multiplex processing. A probe houses the multi-dimensional array and a multiplexer.

摘要： A method of providing connections to an arrangement of multilayer transducer elements of an ultrasonic transducer array includes patterning an electrically conductive layer on a substrate to define a number of traces and a wide-area continuous region. At least a portion of the substrate is then removed to expose both of the upper and lower surfaces of the wide-area conductive region. The exposed upper and lower surfaces are captured between first and second piezoelectric layers such that the conductive layer electrically contacts both of the piezoelectric layers. The captured wide-area continuous region and at least one of the piezoelectric layers are diced to define the array of transducer elements. The traces that are formed during the patterning step are arranged such that there is a one-to-one correspondence between the traces and the electrodes that are defined by segmenting the wide-area continuous region during the dicing step.

摘要： An ultrasonic transducer array has a piezoelectric ceramic layer that is separated in a longitudinal direction into n transducer groups. Each group is separated in a transverse direction into m elements. A double-sided flex circuit has a flexible, non-conductive base layer, through which conductive vias extend and are in electrical contact with a respective element. A conductive layer on a bottom side of the flex circuit is divided into a plurality of electrodes, each of which is in electrical contact with a respective one of the elements. For each group, electrically conductive traces connect predetermined ones of the flex circuit electrodes with external driving circuitry, and are located on a top side of the flex circuit. Transducer groups with different numbers of elements are provided, some with 1.5-D operation (with element pairs stimulated via a common trace) and some with 2-D operation (with separate traces for each element). For embodiments with more than three elements per group, the flex circuit includes more than one base layer. The invention also makes it possible at most two traces located on the top side of the flex circuit for each group, measured in the longitudinal direction. In one implementation, each array group was no wider than 300 .mu.m, each trace was at least 50 .mu.m, and the separation between each via and the nearest trace which is not connected to it was at least 75 .mu.m.

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： CMUT elements are formed on a substrate. Electrical conductors are formed to interconnect between different portions of the substrate. The substrate is then separated into pieces while maintaining the electrical connections across the separation. Since the conductors are flexible, the separated substrate slabs may be positioned on a curved surface while maintaining the electrical interconnection between the slabs. Large curvatures may be provided, such as associated with forming a multidimensional transducer array for use in a catheter. The electrical interconnections between the different slabs and elements may allow for a walking aperture arrangement for three dimensional imaging.

摘要： Electrical connection is provided in a transducer stack through a backing block. A flexible circuit is sandwiched between pieces of acoustic attenuating material. For example, 2 to 200 or more flexible circuits are stacked in alternating layers with pieces of acoustically attenuating material. The alternating layers are then connected together to form a backing block with Z-axis electrical connection. The top surface of the connected backing block includes a plurality of exposed electrical traces from the flex circuit. Since flex circuits are used, the electrical traces are precisely aligned along one dimension. Since pre-formed acoustic attenuating material pieces are used, precise alignment is provided along a second or orthogonal dimension. The substrate holding the electrical traces in the flexible circuits provides more stability and allows for easier connection to circuit boards as compared to individual strips of metal.

摘要： Methods, systems, and probes are provided for medical ultrasound imaging. By using larger segments for transmit than receive or by using a sparse sampling of elements on transmit than used for receive, the number of transmit beamformer channels relative to receive beamformer channels is reduced. Where the transmit waveformed generators of the transmit beamformer channels are positioned within an ultrasound probe, the space and power requirements of the transmit beamformer channels are reduced based on the reduction in number of transmit segments. Different approaches may be used for reducing the number of transmit channels relative to receive segments. For example, a flexible circuit is connected to one side of a multi-dimensional array and defines transmit segments as groups of two or more elements. A different flexible circuit connects on an opposite side of the elements. The different flexible circuit defines receive segments as individual elements or a fewer number of elements than the transmit segments. Alternatively, switching is used to combine elements into single transmit segments. As another alternative, switching or configuring electrode circuits is used to define transmit segments as sparsely-spaced elements and the receive segments as a less sparsely spaced. In yet another approach, the transmit aperture covers a lesser area than the receive aperture, such as through sparse spacing or having smaller overall dimensions.
摘要翻译： 为医学超声成像提供了方法，系统和探针。 通过使用比接收更大的发送段，或通过使用传输上的元素的稀疏采样而不是用于接收，相对于接收波束形成器信道的发射波束形成器信道的数量减少。 在发射波束形成信道的发射波形发生器位于超声波探头内的情况下，基于发射段数量的减少，发射波束形成信道的空间和功率要求被减小。 可以使用不同的方法来减少相对于接收段的发送信道的数量。 例如，柔性电路连接到多维阵列的一侧，并将传输段定义为两个或多个元件的组。 不同的柔性电路在元件的相对侧连接。 不同的柔性电路将接收段定义为单独的元件或者比发射段更少的元件数量。 或者，切换用于将元件组合成单个发送段。 作为另一替代方案，使用切换或配置电极电路来将发射段定义为稀疏间隔的元件，并且接收段作为较少稀疏间隔。 在另一种方法中，传输孔径覆盖比接收孔径小的区域，例如通过稀疏间隔或具有较小的总体尺寸。
