    摘要： The present technique provides for the manufacture and/or use of an ultrasound probe configured to acquire non-imaging data in addition to imaging data. In particular, the ultrasound probe includes a micro-machined ultrasound transducer formed on the surface of a substrate using micro-electric mechanical systems techniques or other techniques associated with semiconductor processing. Non-imaging sensors are formed on the substrate, either on the surface or the interior, or on a substrate proximate to the substrate upon which the transducer is formed. The non-imaging sensors may be used to acquire non-imaging data in conjunction with the acquisition of imaging data by the transducer.

    摘要： A continuous, non-invasive fetal heart rate measurement is produced using an ultrasound probe positioned on the abdomen of the mother. The ultrasound probe includes a plurality of ultrasound transducers that are positioned within a housing having a transmission surface. The transmission surface is configured to defocus the individual ultrasound beams created by the plurality of ultrasound transducers. The transmission surface defocuses the ultrasound beam and creates a wider area of coverage for the ultrasound probe. The controller contained within the heart rate monitor selectively activates different combinations of the plurality of ultrasound transducers to reduce the signal-to-noise ratio while allowing the ultrasound probe to locate the fetal heart beat and subsequently increase the signal-to-noise ratio during continuous heart rate monitoring.

    摘要： A curved sensor device, such as an ultrasonic transducer array, is fabricated from a flat micromachined sensor (such as cMUT or pMUT) array constructed using micromachined electromechanical systems (MEMS) techniques. The device comprises: a support structure comprising a spine having a profile that is generally curved and a multiplicity of teeth extending from one side of the curved spine; and a multiplicity of sensors built on the support structure. The spine can be bent forward or backward and attached to a curved front face of a support member, thereby causing the sensors to adopt a curved array.

    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.
