    摘要： A micromachined ultrasonic transducer array comprising a multiplicity of cMUT cells built on a substrate. Each cMUT cell comprises a compliant support structure built on the substrate, a membrane supported over a cavity by the compliant support structure, a first electrode supported by the membrane, and a second electrode that forms a capacitor with the first electrode, the cavity being disposed between the first and second electrodes. The compliant support structure uncouples the non-membrane outer surface of each cMUT cell from the supporting substrate.

    摘要： Method and apparatus for visually depicting a health care treatment regimen for a given medical diagnosis including a substantially flat planar platform and a plurality of groupings of geometric members which are representative of various events which go to make up the treatment regimen. The geometric members of a particular grouping preferably are equally sized and of a coloring that is unique to the grouping. All geometric members are releasably securable to the platform and/or one another to permit their securement to the platform and/or to one another in positions denoting the existence of, position of and order of occurrence of their represented events within the treatment regimen.

    摘要： A system for improving the acoustic performance of an ultrasound transducer by reducing artifacts within the acoustic spectrum is disclosed. The system includes an acoustic layer having an array of acoustic elements, a dematching layer coupled to the acoustic layer and having an acoustic impedance greater than an acoustic impedance of the acoustic layer, and an interposer layer coupled to the dematching layer and comprising a substrate and a plurality of conductive element. The interposer layer is formed to have an acoustic impedance lower than the acoustic impedance of the dematching layer. The ultrasound transducer also includes an integrated circuit coupled to the interposer layer and electrically connected to the array of acoustic elements through the dematching layer and the interposer layer.

    摘要： An ultrasonic transducer device comprising: an ultrasonic transducer array micromachined on a substrate; flexible electrical connections connected to the transducer array; and a body of acoustically attenuative material that supports the substrate and the flexible electrical connections. The acoustic backing material may contain additional features, such as tabs or notches, for use in positioning the transducer on fixtures during manufacturing or positioning the transducer within a housing during final assembly. Tabs or other features that are used only during manufacturing may be subsequently removed from the device. The MUT device itself may also be thinned so as to provide flexibility as desired. The backing material is preferably matched in acoustic impedance to the silicon wafer so as to prevent reflection at the interface of any acoustic energy propagating rearward, i.e., in the direction away from the device front surface. The backing material may also possess a high thermal conductivity to assist in removal of heat from the device.
