A deployable ultrasound imaging device is operably connected to an ultrasound imaging system including a processing unit configured to operate the transducer and the individual segments in order to emit ultrasound signals from the segments and to receive ultrasound signals from the structures surrounding the segments. The ultrasound imaging system/processing unit can process the transmitted and received signals by beamforming to direct the ultrasound signals emitted from the segments in order to provide data for an ultrasound image of the desired structure(s). The ultrasound imaging system/processing unit mechanically or acoustically determines the position of the individual segments with regard to one another to determine the angular position of the segments with regard to one another. Using the angular position, the ultrasound imaging system/processing unit can apply a beamforming correction to the ultrasound signals emitted from and/or received by the segments in order to produce an accurate ultrasound image.

System and method of signal processing for ultrasound arrays with mechanically adjustable transducer shapes

Certain embodiments of the present technology provide systems and methods that provide reduction of multiline artifacts in Doppler imaging. Certain embodiments provide for various ensembles of transmit beams at different spatial locations and overlapping receive beams between the locations. Certain embodiments provide for calculating various auto-correlation estimates based on the received beams and then combining the auto-correlation estimates to create an image. In certain embodiments, combining the auto-correlation estimates comprises applying a linear interpolation filter that decreases the weight applied for receive beams that are spatially located further away from the transmit beam.

Reduction of multiline artifacts in doppler imaging

A method is provided to simultaneously acquire two ultrasound images. A first set of ultrasound pulses are transmitted at a first frame rate utilizing a first mode of operation. The echoes from the first set of ultrasound pulses are received. A second set of ultrasound pulses are transmitted at a second frame rate utilizing a second mode of operation. The first and second frame rates are different. The first set of ultrasound pulses defines an entire image, while the second set of ultrasound pulses defines a partial image. The echoes from the second set of ultrasound pulses are received, and the echoes from the first and second sets of ultrasound pulses are displayed as a single image.
