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 ultrasound transducer array includes a multiplicity of subelements interconnected by a multiplicity of microelectronic switches, each subelement comprising a respective multiplicity of micromachined ultrasound transducer (MUT) cells. The MUT cells within a particular subelement are hard-wired together. The switches are used to configure the subelements to form multiple concentric annular elements. This design dramatically reduces complexity while enabling focusing in the elevation direction during ultrasonic image data acquisition.

The probe also includes a lead-screw nut positioned about the lead screw such that the lead-screw nut engages the threads and such that the lead-screw nut and the lead screw can move relative to one another via the threads, a transducer configured to move vertically with the lead screw, and an enclosure surrounding the transducer, wherein the enclosure includes a probe face configured to hold fluid and engage a wave emission target such that waves from the transducer can enter the target. Further, the probe includes a capture feature capable of engaging the lead-screw nut such that the lead-screw nut is vertically fixed relative to the probe face and such that the lead screw moves away from the probe face when rotating within the lead-screw nut in a first direction and moves toward the probe face when rotating within the lead-screw nut in a second direction opposite to the first direction while the lead-screw nut is engaged by the capture feature.

摘要： Methods and non-transitory computer readable media that store executable instructions to perform a method for reducing motion artifacts in shear wave measurements are presented. Accordingly, reference pulses are delivered to a common motion tracking location (CMTL) and a plurality of target locations in a region of interest (ROI) to detect corresponding initial positions. Further, a shear wave is generated and tracked in the ROI using tracking pulses delivered to the CMTL and the plurality of target locations for determining corresponding displacements. Additionally, an average displacement of the CMTL is computed. Further, a motion corrected displacement for a target location in the plurality of target locations is estimated based on a displacement of the target location at a particular time, a corresponding displacement of the CMTL measured proximate in time to the measurement of the displacement of the target location and the average displacement of the CMTL.
