摘要： An acoustic array is helical or twisted about or around an azimuth axis. For example, one end of the array has an emitting face at 0 degrees, but the other end has an emitting face at 20 degrees. The elements in between gradually transition between the different rotations. Different apertures of the twisted array may be used to scan different generally radial diverging planes for three-dimensional imaging. The different amount of relative rotation associated with each aperture cause angular elevation spacing of the planes. For use in a catheter, a single row of elements may be used to scan electrically a volume.

摘要： Multiple twisted or rotated arrays are provided. For example, a memory alloy may allow manufacture of multiple rows of elements on a flat substrate. The memory of the alloy is activated to twist different rows in different ways, such as two adjacent substantially parallel but oppositely rotated arrays. By selecting different apertures along a given twist, different planes are scanned due to the difference in direction of the elements of the aperture. By selecting different apertures on differently rotated arrays, a larger volume may be scanned.

摘要： Synthetic transmit aperture is provided for three-dimensional ultrasound imaging. A transducer may have separate transmit and receive elements. Broad beams are transmitted, allowing fewer transmit elements and/or more rapid scanning. A multidimensional receive array generates data in response to sequential transmissions, such as transmissions from different angles. The data is combined to increase resolution. A transducer array with offset transmit elements for forming a transmit line source may be used.

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.
摘要翻译： CMUT元件形成在基板上。电导体形成为在衬底的不同部分之间互连。然后将衬底分离成片，同时保持穿过分离的电连接。由于导体是柔性的，所以分离的基板可以定位在弯曲表面上，同时保持板之间的电互连。可以提供大的曲率，例如与形成用于导管的多维换能器阵列有关。不同板坯和元件之间的电互连可以允许用于三维成像的步行孔布置。

摘要： A transducer array is connected with a catheter housing. As the transducer array is rotated, the catheter housing also rotates. As a result, at least a portion of the catheter housing twists about a longitudinal axis. By applying rotation in a controlled way, such as with a motor, a plurality of two-dimensional images for three-dimensional reconstruction may be obtained. The rotation of the catheter housing may limit the total amount of rotation of the array, such as rotating the array through a 90 degree or less amount of rotation about the longitudinal axis. The housing of the catheter is formed with a soft section. The softer material allows for a greater amount or increased ease for twisting the catheter.
摘要翻译：换能器阵列与导管外壳连接。当换能器阵列旋转时，导管壳体也旋转。结果，导管壳体的至少一部分围绕纵向轴线扭曲。通过以受控的方式，例如用电动机施加旋转，可以获得用于三维重建的多个二维图像。导管壳体的旋转可以限制阵列的总旋转量，例如使阵列围绕纵向轴旋转90度或更少的旋转量。导管的外壳形成有柔软的部分。较软的材料允许更大的数量或更容易扭转导管。

摘要： An RF amplifier including first and second FETs which are interconnected to function as a single transistor with improved gate. An input signal is applied across the gate and source of the first FET, and an output signal is obtained across the drain and source of the second transistor. RF coupling of the FETs is provided by first and second serially connected transmission lines connected between the drain of the first FET and the gate of the second FET. A third transmission line connects the common terminal of the first and second transmission line to circuit ground. In a preferred embodiment, the amplifier comprises a monolithic circuit formed in gallium arsenide with the transmission lines comprising microstrip.
