Phase Modulation Beamforming for Ultrafast Plane-Wave Imaging. [PDF]
IEEE Trans Ultrason Ferroelectr Freq Control, 2020 In order to improve the spatial resolution for high-frame-rate imaging, a new image formation approach is proposed based on introducing very weak aberration into received data, then combining the multiple results by taking the pixel-wise standard deviation of multiple aberrated images and subtracting the result from the delay-and-sum image.

Plane-Wave Imaging Improves Single-Track Location Shear Wave Elasticity Imaging. [PDF]
IEEE Trans Ultrason Ferroelectr Freq Control, 2018 Single-track location shear wave elasticity imaging (STL-SWEI) is immune to speckle bias, but the quality of the images is depth dependent. We hypothesize that plane-wave imaging can reduce the depth dependence of STL-SWEI. To test this hypothesis, we developed a novel technique known as plane-wave STL-SWEI (pSTL-SWEI).

Fast, Low-Frequency Plane-Wave Imaging for Ultrasound Contrast Imaging. [PDF]
Ultrasound Med Biol, 2018 Plane-wave ultrasound contrast imaging offers a faster, less destructive means for imaging microbubbles compared with traditional ultrasound imaging. Even though many of the most acoustically responsive microbubbles have resonant frequencies in the lower-megahertz range, higher frequencies (>3 MHz) have typically been employed to achieve high spatial ...

Noise Equalization for Ultrafast Plane Wave Microvessel Imaging [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2017 Ultrafast plane wave microvessel imaging significantly improves ultrasound Doppler sensitivity by increasing the number of Doppler ensembles that can be collected within a short period of time. The rich spatiotemporal plane wave data also enable more robust clutter filtering based on singular value decomposition.

Methods for Grating Lobe Suppression in Ultrasound Plane Wave Imaging
Applied Sciences, 2018 Plane wave imaging has been proven to provide transmit beams with a narrow and uniform beam width throughout the imaging depth. The transmit beam pattern, however, exhibits strong grating lobes that have to be suppressed by a tightly focused receive beam

Plane wave imaging combined with eigenspace-based minimum variance beamforming using a ring array in ultrasound computed tomography [PDF]
BioMedical Engineering OnLine, 2019 Background Ultrasound computed tomography (USCT) is usually realized with a ring array. It can provide better imaging performance and more tissue information by emitting and receiving the ultrasound signal in different directions simultaneously. However,

High-Frequency Multipulse, Plane-Wave Acoustic Contrast Imaging [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2020 Multipulse (MP) ultrasound contrast agent (UCA) imaging is a method to increase the contrast-to-background (CBR) ratio in regions of blood flow. Plane-wave imaging allows high frame rates, and with high-frequency ultrasound, fine-spatial and temporal resolution. MP and plane-wave imaging have not been applied to high-frequency ultrasound.
