Ultrasound contrast plane wave imaging
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2012Monitoring the accumulation of microbubbles within tissue vasculature with ultrasound allows both molecular and perfusion imaging. Unfortunately, conventional imaging with focused pulses can destroy a large fraction of the microbubbles it is trying to follow.

Plane-wave phase-coherence imaging for NDE
NDT and E International, 2017Abstract In ultrasound imaging with arrays the frame rate is limited by the number of insonifications of the inspected medium. In the limit, a single omnidirectional or plane wave insonification (OWI or PWI, respectively) would provide the maximum frame rate.

Extended Aperture Image Reconstruction for Plane-Wave Imaging
SSRN Electronic Journal, 2023B-mode images undergo degradation in the boundary region because of the limited number of elements in the ultrasound probe. Herein, a deep learning-based extended aperture image reconstruction method is proposed to reconstruct a B-mode image with an enhanced boundary region.

Machine learning for plane wave imaging
Proceedings of the Annual British Conference on Non-Destructive Testing, 2023Phased array ultrasonics have enabled the recording of an ever-increasing amount of data from the inspection targets. With the latest advancements in total-focusing method with plane wave imaging the amount of data has increased exponentially when compared to conventional ultrasonic methods.

Virtual Array Plane Wave Imaging
2021 IEEE International Ultrasonics Symposium (IUS), 2021The Plane Wave Imaging (PWI) method, originally developed for medical images, was extended in various works for its use in Non-Destructive Testing (NDT). In this field the most frequent scenario presents the difficulty of refraction at the surface of the test piece, which must be accounted for the calculation of focal laws.

Superharmonic and Microultrasound Imaging With Plane Wave Beamforming Techniques
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2023Superharmonic contrast imaging (SpHI) suppresses tissue clutter and allows high-contrast visualization of the vasculature. An array-based dual-frequency (DF) probe has been developed for SpHI, integrating a 21-MHz, 256-element microultrasound imaging array with a 2-MHz, 32-element array to take advantage of the broadband nonlinear responses from ...
