摘要： A method is described for making a piezoelectric composite for building an acoustic transducer from two or more pieces of piezoelectric material. Each piece of material is cut to form slots or trenches having a uniform pitch spacing and material portions of uniform width such that the material portions of one piece may be received within the slots or trenches of the other. The pieces are then interdigitated and joined to make the piezoelectric composite.

摘要： Spiral, sparse spiral, substantially spiral or substantially sparse spiral transducer arrays comprising capacitive micromachined ultrasonic transducer elements disposed on a silicon substrate, and ultrasound imaging systems employing same. The transducer elements are respectively coupled to a plurality of amplifiers. Imager electronics are coupled to each of the amplifiers and drives the transducer elements and/or generates an output of the spiral transducer array. The amplifiers may be located in the silicon substrate containing the transducer elements, or on a separate substrate that is interconnected to the substrate containing the transducer elements using bumps, for example. Electrical interconnection to the transducer elements may readily be achieved without interfering with the acoustic output of the transducer elements.

摘要： According to the present invention, an ultrasonic probe for use with a remote ultrasonic imaging system is provided, having a multielement transducer with an upper surface and a lower surface. An ultrasonically attenuative backing material adjoins the lower surface of the multielement transducer. The attenuative backing material is disposed within a container. A circular track is mounted to the container, and a flexible assembly and a carrier band are attached to the container. The carrier band may be operable to rotate the multielement transducer about an axis defined by the circular track. Alternatively, the circular track may be operable to rotate the multielement transducer. Additionally, a method of forming near real-time images of an object in a plane that is oblique to the axis of rotation of the multielement transducer is provided.

摘要： A capacitive microelectromechanical ultrasound transducer array with improved efficiency and durability is provided. Efficiency is provided by stacking CMUTs in the range dimension (i.e. away from the face of the transducer). A plurality of chambers and associated membranes are stacked along a range dimension or parallel to the direction of acoustic radiation. Because the CMUT transducer element is stacked, ultrasound is transmitted through the plurality of chambers, amplifying the response of the transducer element. Durability is increased within the transducer by filling the chamber with a nongaseous filler. A liquid, polymer, solid or plasma fills the chamber or chambers. The nongaseous filler allows movement of the membrane for transducing between acoustic and electrical energies, but prevents collapse or bottoming out of the membrane.

摘要： A method and system for coherent ultrasound imaging of induced, distributed source, bulk acoustic emissions. First, bulk acoustic emissions are induced from distributed sources within an object from a single transmit event of non-acoustic energy. Next, coherent signals are stored for each of a selected number of transducer elements of a transducer array receiving the induced bulk acoustic emissions. The stored coherent signals can then be focused to form an ultrasound image. Additionally, motion of an imaged object can be detected using induced, distributed source, bulk acoustic emissions.

摘要： A plurality of piezomaterial bodies, such as panels or slices, are merged together to form a larger piezomaterial body. For example, a 0.75×22 cm polycrystalline piezomaterial body is formed, where the distances are along lateral or footprint dimensions. The thickness of the piezomaterial body is substantially less than either of the distances along first and second lateral dimensions that define the footprint. Preferably, each piezomaterial body has a panel shape, and a plurality of panels are merged to form a large multi-panel.
