    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： 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： 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： A memory alloy is used during manufacture of a transducer. The memory of the alloy may correct for deviations or bending during manufacture, such as a superelastic alloy returning an array to a flat state after being twisted during handling. The memory of the alloy may cause a desired change in array geometry during manufacture, such as a shape memory alloy twisting an array into a curved or helix due to applied heat. The array may be fixed in place by the memory alloy or bonding after positioning by the memory alloy, preventing further substantial alteration.

    摘要： A bulk semiconductor oscillator subassembly is carried on a support pin. The oscillator assembly includes a semiconductor diode mounted on the pin with one terminal connected thereto. The other terminal is connected to one end of an input coupling loop which has its other end connected to the pin through a by-pass capacitor. Biasing voltages are applied to the diode via a lead connected to the loop. The loop is coupled to a Yttrium Iron Garnet (YIG) sphere which serves as a resonator. The resonant frequency of the resonator is tuned by adjusting a DC magnetic field applied thereto. The output is obtained by an output loop which is located orthogonally with respect to the input loop and coupled to the YIG whereby the input and output loops are coupled through the YIG resonator.
