摘要： The reconfigurable ultrasound array disclosed herein is one that allows groups of subelements to be connected together dynamically so that the shape of the resulting element can be made to match the shape of the wave front. This can lead to improved performance and/or reduced channel count. Reconfigurability can be achieved using a switching network. A methodology and an algorithm are disclosed that allows the performance of this switching network to be improved by properly choosing the configuration of the switching network.

摘要： A reconfigurable linear array of sensors (e.g., optical, thermal, pressure, ultrasonic). The reconfigurability allows the size and spacing of the sensor elements to be a function of the distance from the beam center. This feature improves performance for imaging systems having a limited channel count. The improved performance, for applications in which multiple transmit focal zones are employed, arises from the ability to adjust the aperture for a particular depth.

摘要： An integrated switch matrix for reconfiguring subelements of a mosaic sensor array to form elements. The configuration of the switch matrix is fully programmable. The switch matrix includes access switches that connect subelements to bus lines and matrix switches that connect subelements to subelements. Each subelement has a unit switch cell comprising at least one access switch, at least one matrix switch, a respective memory element for storing the future state of each switch, and a respective control circuit for each switch. The access and matrix switches are of a type having the ability to memorize control data representing the current switch state of the switch, which control data includes a data bit input to turn-on/off circuits incorporated in the control circuit. The sensor array and the switching matrix may be built in different strata of a co-integrated structure or they may be built on separate wafers that are electrically connected. If the sensors are arranged on a hexagonal grid, the unit switch cells may be arranged on either a hexagonal or rectangular grid.

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 low-voltage transmit/receive switch that acts to protect sensitive low-voltage electronics from high-voltage pulse signals used to drive an ultrasonic transducer. The low-voltage transmit/receive switch comprises a series resistor and a parallel MOSFET pair. The parallel MOSFETs are low-voltage devices. The low-voltage transmit/receive switch is placed between the output of a high-voltage pulser and the input of a receive pre-amplifier. If dual high- and low-voltage pulsers are used, then the low-voltage pulser is connected so that it is also protected from the high-voltage pulse signals by the low-voltage transmit/receive switch. In an alternative embodiment, the low-voltage pulser and the receive pre-amplifier are protected from the high-voltage pulse signals by a high-voltage transmit/receive switch.
